Volume of water in the calorimeter:| 26. 0 mL| 26. 0 mL| 26. 0 mL| 26. 0 mL| Initial temperature of water in calorimeter:| 25. 3 Â °C| 25. 3 Â °C| 25. 3 Â °C| 25. 3 Â °C| Temperature of hot water and metal in hot water bath:| 100. 5 Â °C| 100. 5 Â °C| 100. 5 Â °C| 100. 5 Â °C| Final temperature reached in the calorimeter:| 31. 6 Â °C| 34. 8 Â °C| 33. 1 Â °C| Â  34. 5 Â °C| Part I: Part II: Metal:| Metal A| Metal B| Metal C| Mass of metal:| 15. 262 g| 25. 605 g| 20. 484 g| Volume of water in the calorimeter:| 24. mL| 24. 0 mL| 24. 0 mL| Initial temperature of water in calorimeter:| 25. 2 Â °C| 25. 3 Â °C| 25. 2 Â °C| Temperature of hot water and metal in hot water bath:| 100. 3 Â °C| 100. 3 Â °C| 100. 3 Â °C| Final temperature reached in the calorimeter:| 27. 5 Â °C| 32. 2 Â °C| 28. 0 Â °C| Part 12: Part I: 1. Calculate the energy change (q) of the surroundings (water) using the enthalpy equation qwater = m ? c ? ?T. We can assume that the specific heat capacity of water is 4. 18 J / (g ? Â °C) and the density of water is 1. 00 g/mL. qwater = m ? c ? ?T m = mass of water = density x volume = 1 x 26 = 26 grams T = T(mix) T(water) = 38. 9 25. 3 = 13. 6 q(water) = 26 x 13. 6 x 4. 18 q(water) = 1478 Joules SPECIFIC HEAT: qmetal = -205 J = 15. 363 g X c X (27. 2 100. 3 C) c = 0. 183 J/gC PART2. Using the formula qmetal = m ? c ? ?T, calculate the specific heat of the metal. Use the data from your experiment for the metal in your calculation. q(water) = q(metal) q(metal) = 1478 Joules q(metal) = m ? c ? ?T m = 27. 776 g ?T = T(mix) T(metal) ?T = 38. 9 100. 5 = 61. 6 C = q(metal) / m x ? T C = -1478 / (-61. 6 x 27. 776 ) C = 0. 864 J / (g ? Â °C) Part 3: 12: For #1 theres a specific heat of 0. 864 J / (g ? Â °C) and that is closest to the specific heat of aluminum. So, for this experiment, lets call your metal aluminum. Now, the percent error formula is this: |experimental actual value divided by actual value| x 100 (|0. 864 0. 900| / 0. 900) * 100 = 4. 00 % For #2, you got 0. 183 J/gC. Comparing it to my list, I would recommend some sort of tin or cobalt meltal. 3. 9(. 39-. 39)x100%)/. 39 = 0% So there is a 0% error. It makes sense, given that the experimental results were THE SAME as the known value. Its the same. There is no error. 4. The easiest error reason is that the calorimeter wasnt a perfect insulator. This is because you must have opened the calorimeter when you added the cold water. Thus, heat was lost not only to the cold water but to the surrounding environment. Also, you might not have waited long enough for the thermometer to read, so the temperature of the hot water was lower than it really was, or the temperature of the cold water was warmer than it really was. Another possible source of error is the increase in heat by stirring due to increased kinetic energy.

The Actors's Nightmare and The 15 Minute Hamlet Essay

The Actors's Nightmare and The 15 Minute Hamlet - Essay Example ay, Christopher Ferdinand Durang is an American playwright, who is known for humor based works, which dealt with important and even controversial issues in an absurd as well as outrageous way. Although, he has been coming up with popular works from the 1980s, his works are achieving immense critical as well as commercial success from late 1990s into 2000s. Some of his best known works through the last three decades includes Sister Mary Ignatius Explains It All For You, Baby With the Bathwater, The Nature and Purpose of the Universe, Titanic, The Idiots Karamazov, Laughing Wild, Naomi in the Living Room, etc, etc. His latest play of Vanya and Sonia and Masha and Spike got the Tony Award for the Best Play for the year 2013. As mentioned above, his plays often dealt with sensitive as well as controversial issues like homosexuality, child abuse, religious activities, etc., in a critical way. As pointed out above, the play was written and performed in early 1980s, and it mainly reflected the experiences of the actors including Durang, particularly how they will react, if they forget their lines while performing on the stage. In 1980s, stage plays garnered sizable audience, more than the current times, and so the pressure was always on the actors to perform without miss every time. With Durang himself being an actor, who have also faced the ‘actors’ nightmare’ of forgetting the lines, this play reflected author’s personal experiences as well as the professional pressure faced by the actors in those times. In addition, with the issues like homosexuality and child abuse coming into the public domain in 1980s, more than the previous decades, Durang’s plays were maximally relevant to those times. â€Å"There was a time in the 1980s when Christopher Durangs absurdist dark comedies turned up on every stage in Central Florida, and audiences wer e used to his tales of dysfunctional parochial-school students and nuns with guns.† (Maupin). Durang’s take on these

Environmental policies - Research Paper Example As a result of the popularity of this issue, there have been key debates on whether the challenge it posses is dangerous for the world with another side dismissing global warming as an affair that is dangerous and does not exist although the two sides identify the importance of protecting the levels of greenhouse emissions into the atmosphere. This essay focuses on the challenging issue of global warming. The essay will provide a brief definition of global warming and engage in a discussion of global warming and especially on its key definitional aspect of climate change. Thereafter, the essay identifies the reasons that contribute to the aspect of climate change while identifying the main cause of climate change, which is the greenhouse gases emission. The essay will also identify the main responses to climate change and in particular, the main issues of adaptation to climate change and mitigation processes. Before engaging on any discussion on global warming, it is essential to und erstand what global warming means. By its very name, global warming is the increasing temperatures in the atmosphere of the earth and in oceans. It is important to differentiate between the weather and the climate of the world. In this case, the weather in a particular area includes temperatures, the amount of rainfall experienced in a place, the cloud cover, and the wind speed experienced in the place. On the other hand, the climate of a region or a place is quantified by finding the average of the weather in the place (Fern, 2009). Hence, the weather of a place could be defined as dry and hot, cool and wet, or even cool and dry while the weather could be sunny, rainy, windy, or any other type of weather. It is evident that the weather of a region could change anytime. This implies that the climate of a region could also change, which explains the phenomenon the world currently experiences in relationship to global warming as the world becomes hotter and hotter each day. Evidence o f Climate Change The last two decades have remarkably been characterized by the changes in the climate of the world. In this case, the 1980s and 1990s were noted as very warm years and this was the beginning of the issue of global warming since this period ushered in the changes in world climate (Houghton, 2004). In these two last decades of the 20th century, climatic records indicate that there have been issues of climate change with the world’s climatic conditions growing hotter and hotter. Case in point, there has been evidence of unusually strong winds in Europe with the early morning of 16 October 1987 experiencing blowing down of â€Å"over fifteen million trees in the southeastern part of England and in its capital of London† (Houghton, 2004, p.2). Most recently, the world has experienced its fair share of disasters resulting from typhoons and hurricanes that have brought devastating effects on the environment with the effects of these challenges felt on the liv elihoods of people and on their lives. Rainfall patterns have also changed, which is part of the climate changes that the world continues to experience. In this case, the world has experienced increasing incidents of strong rains that lead to flooding while other areas have experienced low

LEGAL ASPECTS OF HOTEL MANAGEMENT Essay Example | Topics and Well Written Essays - 1000 words

LEGAL ASPECTS OF HOTEL MANAGEMENT - Essay Example Modern players in the hospitality industry need to be aware that administering hotel includes the likelihood for the managers, supervisors and owners to be subject to several legal liabilities when it comes to handling the employees. Hence, the aim of this paper is to offer an open treatise that covers the relationship between the hotels and their employees, and based on common law contracts, tort claims, non-discrimination laws, casualness and antitrust laws. Discussion Most employee-relation laws in the hospitality industry are designed to restrict, control and even prohibit certain actions in which the firms could be willingly or unwillingly be non-complying with labor-related ethical plus social standards (Hayes & Ninemeier, 2009). In particular, the hospitality industry has become highly sensitive to both economic factors and competitive marketplace condition, such that the workplace conditions placed on the industry are significant due to the myriad labor risks and employment-r elated disputes (Barth, 2006). The laws range from recruitment standards, to workplace training requirements, remunerations, to environmental and health concerns. This entails a range of issues such as labor disputes, wage and hour compliance, obligation to immigration laws, labor-force authorization regulations as well as observance of nondiscrimination practices. In addition, there is the requirement for the employee’s welfare to be based on OSHA and environmental laws. Firstly, companies in the hospitality industry are now increasingly being held responsible for their employees out of worksite deeds. In particular, firms are now experiencing liability for accidents or injuries caused by their employees to third parties, with damages comprising loss of property, pain, physical and emotional suffering, legal fees, lost wages and medical expenses.. The hospitality firms are now required by law to avoid any unreasonable acts or roles by their employees that can present possibl e risks to third parties. This became apparent in the case of Faverty vs. McDonald, whereby a hospitality industry employee was involved in a serious road accident that injured another motorist. Hence, the court ruled that McDonald was liable to the damages since it forced the worker to operate so many hours nonstop even as they were aware that the employee drove himself home thus a serious risk not just to himself but also to other people and motorists (Barth, 2006). This case set a precedent for other lawsuits in the industry, and which reveals that hospitality companies are not just required to have reasonable policies regarding their employees working hours and wages, but also have a legal duty to enforce the offsite personnel wellbeing in order not to harm other persons wellbeing. As such, The Fair Credit Reporting Act calls for the management to have well-documented structures in which their employees will use to identify, report, and react to both real and probable hazards (B arth, 2006). They are also required to have handbooks and guidelines on safe practices, processes and controls which are particular to a given hazards, and that such guidelines attains or exceed the requirements stipulated under the Act. Moreover, the hospitality compa

The in-game advertising industry Essay Example | Topics and Well Written Essays - 500 words

The in-game advertising industry - Essay Example Business organizations have been very quick to realize the potential profit gain from this segment. Massive Incorporated, which is the world’s first video game company, operates with the mission of â€Å"aggregating the gaming audience to deliver advertising across a network of premier video titles and providing measured results on consumer interaction with the advertising.† Double Fusion is an Israeli in-game advertising company established in the summer of 2004. The business model of Double Fusion is very much similar to that of Massive. The product line of Double Fusion ranges from dynamic advertisements, integrated advertising, and â€Å"around game† inventory. In Game Advertising (IGA) seeks t o provide advertising services with its global computer video game media and advertising network. As opposed to Massive and other aforementioned competitors, IGA’s network encompasses multiple platforms including PC, console and mobile gaming and offer both stat ic and dynamic advertising. Together with Massive, Double Fusion and IGA Worldwide captures the largest market shares. Some smaller start-ups and players in the video game industry are also taking the challenge of in-game advertising.Despite the rapid growth of the video gaming industry, it also faces numerous challenges. It should be noted that customers now demand the creation of video games which have more sophisticated story lines and graphic improvements. On the other hand, the average commercial life of a video game has significantly dropped to less than one year.

Global Marketing and the Digital Revolution Research Paper

Global Marketing and the Digital Revolution - Research Paper Example line, the development of the paperless society and the increasing influence of electronic money transfer, the innovation in mobile apps and internet enabled mobile phones, the development of electronic data exchange (EDE) and the increasing development of social media represents some of the developments arising out of the digital revolution. The advent of the internet and its related social media networks has significantly affected and influenced the concept of marketing and the specific roles of marketing professionals (Jurras, 2012). Social media networks such as Facebook, instagram, pinterest and twitter are forever transforming the landscape of the marketing function and how consumers interact with each other, products and organizations. Jurras argues that with many consumers having online presence and finding it increasingly convenient and safe to engage in online purchases and payments, only firms with an effective social media strategy will achieve a cutting edge in the highly competitive global industry. Social media networks represent an online community of customers with shared attributes, characteristics and interests. These social media sites employ virtual and internet accessible technologies such as smart phones and tablets to facilitate real time interaction and connectivity of online consumers. The customers share their thoughts, experiences with products and organizations, their perceptions regarding the ability of certain products to meet their needs and preferences, and their likes and dislikes about particular brands (Field, 2013). Astute social marketers are increasingly recognizing the importance of social media sites, especially instagram, to interact with the online consumers, develop and enhance brand awareness, and implement their market communication strategies and campaigns. Field (2013) observes that small and local businesses are no longer disadvantaged in regards to size and financial capital because they do not need to be

Research design and data analysis, discussions and recommendations Paper

Design and data analysis, discussions and recommendations - Research Paper Example Likewise, the findings indicate there is no significant difference between the customers’ rank and the dependent variables (food quality, hotel staff service quality, and room quality). Management should accept the two null hypothesis statements. 1. Ramada took several steps to define the research questions. First, the researchers focused on different services offered by the company. The first group of services focused on customer’s criticism of the menu variety. Next, the questions veered towards the customer’s valued received in exchange for the amount paid. Third, the question veered towards determining if the customers’ liked the service promptness. Fourth, the question zeroed in on Ramada’s service quality. Fifth, the service focused on the resort’s food quality. Last, the questions veered towards the beverage quality served in the Ramada resorts. Further, management has to answer some questions. The questions focused on the hiring of the right resort employees. Next, management had to answer questions pertaining to the enhancement of the current training of employees. Training is one of management’s secret ingredients to increasing the current and future customers’ loyalty. Management must answer queries in the area of increasing the current motivation practices. Motivation increases the customer’s eagerness to return to Reamada resorts. Management must ensure all questions are answered by espousing the importance of hiring and training employees who will pamper each clients from check-in to check-out. The process was appropriate. Focusing on hiring the best employees will ensure better customer service. Training the best employees will ensure higher quality service quality. Motivation will ensure employees will continue to excel in all their individual tasks and responsibilities. 2. The secondary data played a vital part in the exploring part of the research (Craig 25). The
