Determine Specific heat capacity of water and metals Essay

Determine Specific heat capacity of water and metals - Essay Example During the experiment, precautionary measures were observed in order to prevent accidents by adhering to laboratory rules and regulations. While handling hot objects, direct contact was avoided and tongs were used to handle the metals. While transferring metals, splashing of hot water was prevented through gentle removal and dipping of the metal and thermometers in the beakers. To ensure that the metal cooled enough, running cold water on the metal surface and then dried. Measure the mass of the empty beaker record it, and then pour 500ml or 0.5 kg water into the beaker and measure the total mass. The mass of water is determened by subtracting the mass of the beaker from the total mass and recorded the mass (m). The table illustrates the data collected in the respective timeline during the experiment and recorded immediately. The data helps in drawing a chart that can be use to determine the value of R2 that is the line of best fit that is supposed to be 1. The chart is drawn from the data in Table 3 which will facilitate determining the closeness to the theoretical R2=1. From the chart the R2= 0.9913 which is very close to the optimum theoretical value. The equation of the trend line is y = 50.774x - 1266.6 that provides for a gradient of 50.774 and with a constant value of -1266.6. The specific heat capacity obtained for Water trial1 was (4076.25 J kg-1 â„Æ' -1) and trial2 (4080 J kg-1 â„Æ' -1). The specific heat capacity obtained for Aluminium was (890.37 J kg-1 â„Æ' -1) and that of Copper was (387.738 J kg-1 â„Æ' -1). Comparing these values with theoretical values, water, aluminium, copper are respectably (4185 J kg-1 â„Æ' -1), 897 (J kg-1 â„Æ' -1) and 385 (J kg-1 â„Æ' -1) (The Engineering Toolbox, n.d.), we can note a slight difference in the values. The values are not exactly the same as the theoretical values. The experimental error  is 2.25%. There are some explanations for this. Heat is lost to the surrounding during the transfer of

Economic Growth and Economic Fluctuations Essay

Economic Growth and Economic Fluctuations - Essay Example The economic theories and models examined would be the Solow Model, the human capital theory and screening model. The effects of governmental policies on the openness of the economy will also be examined here. The data given will serve as guiding force in the determination of the ability of our study country to achieve rapid short-term economic growth and long-term sustenance of a steady rate of growth. When charged with the responsibility of determining the best policy to foster long-term economic growth, it is vital to analyze many economic factors and trends. These factors include the impact of productivity, savings and depreciation on the economy as well as the economy's ability to sustain long-term growth under the given circumstances. In so doing, the Solow Model can serve as a general guidance in determining whether an economy can sustain long-term growth given the present combination of factors. In order to examine this it is vital to offer an operational definition of Solow's model. Solow's model is a model the increase in the capacity of a country's economy to produce goods and services over time. This increase theoretically implies that the well-being of the citizens will improve over time. According to Solow the increase can be determined utilizing a formula whereby the GDP is determined by combinations of inputs. Solow simplifies this very intricate function by presumi ng certain factors are held constant. One of the most fundamental simplifications is the assumption that a single good is produced by the economy in question. In so doing, the GDP is greatly simplified and its implications are clearly depicted. The other assumptions of the Solow model include the assumption that all data is collected on a time continuum, a single good is produced with a constant technology, there is no governmental or international trade, all factors of production are utilized to their full capacity, the growth within the labor force is constant. Utilizing the relationship existent between the savings and the investment and extending the Solow model further, we can assume that the depreciation rate, the amount of capital depreciation and the change in capital over time are held constant. The implications of this are such that in the long-run, we are able to yield a production function whereby Y = AF(K, L). Essentially, it establishes a relationship between capital stock and the economic output. Taking this one step further and assuming that labor input is held constant and there is a positive correlation between changes in capital and output we can see that in time additions to capital stock will yield additions in output. This relationship can be expressed in terms of labor and economic output. In so doing, we can determine the economic output for each individual in the society. The pertinent equation is y=Y/L and can be graphically depicted as follows: The Impact of Savings Rate on Long-term Economic Growth After having examined the production function, we need to examine a prudent question-Is it possible for our country of study to catch up with richer countries and at what rate will it occur In examining that question, we need to realize that according

Several Choices Available - Highlighted - Essay Example Dealing with the piracy to the software is a herculean task which has proven difficult even to the most developed parts of the world. Intellectual property right allows for the owner of an invention to posses the ownership of such creativity. Some of the ways in which intellectual property right ensures that the innovator is protected is through provision of patent, copyrights, designs as well as trademark. One of the most rampant problems that has increasingly grown in the world of software is its unlawful duplication and sharing as well as the piracy. Though software piracy has been a problem in United States and North America, the rate of piracy would not be compared to that of the other parts of the world. (Craig, P., Honick, R., & Burnett, M., 2005) This is majorly because in several parts of the world, copyrights and patent laws specifically those in the United States are not recognized in such places. Additionally, because it is quite easy to distribute the software, it becomes difficult to control the intellectual property rights beyond borders. For software privacy to be ensured there is a need for amalga mation of technology, education, and legislation that would be accompanied by enforcement. (Greg, A., 2009)The policies that need to be developed should be in a manner that ensure promotion of anti-piracy but in no means deterring the use of the software by the legal users. The illegal copying and sharing of software applications and packages that violates patent laws and software licenses would be referred to as software piracy. (Johns, A., 2009) Like laws that protect any other intellectual properties, such as literature, music and movies, software, Software is also protected by such laws. However, software is a new entrant within the intellectual property protection. Software piracy is not always considered as stealing considering that users only do that through making of copies as well as

How did the discovery of the Americas impacted European life Essay

How did the discovery of the Americas impacted European life - Essay Example In this respect, Columbus’ discovery of a New World was a disappointment, because he had gone in search of western access to Japan and India. He failed to return to Spain loaded with spices. But next Spanish-backed explorations soon proved the value of the newly discovered lands (Kishlansky 358). The discoveries of Americas in the first place influenced the economic development of Europe. There began to emerge a colonial system that has accelerated the capitalist production in Western Europe and contributed to the accumulation of the large sums of money in the hands of bourgeoisie. The latter opened the door to the organization of the large enterprises. The discovery of new lands could not but influence the worldview of the European people, their religious, philosophical and religious thought. The discovery of Americas had also a huge impact on the European habits, because the first traders brought to Europe such integral parts of everyday life like chocolate and tobacco. Thes e products were unknown in Europe before. The influence of tobacco and drinking chocolate could not be questioned. Thus, the current paper discusses the impact that the discovery of Americas had on the Western European economy, on religious and philosophical thought, and on people’s everyday habits in the early modern period. ... The monopoly on these new markets guaranteed the rapid accumulation of capital in the countries of the Western Europe. There began the so-called â€Å"price revolution† (Fischer 68). It was caused by the import of large amounts of American gold and silver to Europe. During the 14th century the total amount of hard money in Europe increased more than 4 times. The large inflow of relatively cheap gold and silver led to the sharp drop of their value and to the significant increase in prices for agricultural and industrial products. The revolution in pries has strengthened the urban and rural bourgeoisie and advanced their incomes. The feudal lords were broken. The poorest peasants and workers suffered great damages due to the price revolution. The prices for agricultural products have grown to a much greater extent than for the luxuries (Fischer 77). In Spain, for example, due to the increasing costs a number of goods became uncompetitive. This was one of the reasons for the decl ine of the industry and commerce in this country. However, due to the same reasons the Dutch merchants came at the international stage as the leading trade agents. Gold inflation had a great impact on the industrial development, accelerating the transition to capitalism manufacturing. There was a sharp decline in the wages of the workers. Thought, the nominal value of the wages increased, it was not sufficient in comparison with price increases. In France, price revolution lead to the numerous peasants’ revolts, because they could not cope with burdensome taxes and rent they had to pay their lords. Naturally, when the prices for the goods of the first necessity became impossible, it led to the increasing discontent among masses (Spielvogel

Literacy Narrative Essay Example | Topics and Well Written Essays - 750 words - 2

Literacy Narrative - Essay Example At a moment, he had no prior role in my life while next moment he proved out to be a blessing in disguise, defining for me some purposefulness in life. I never had much regard for literacy and education but that event was pivotal in making me question my own ignorance and beliefs. A turning stone We were born and brought in Middle East, where Arabic was our primary native language while ability to speak English was an add-on. I never did much effort trying to learn other languages or seek education since Arabic sufficed all my needs to communicate on daily basis. I still can clearly visualize that day when I met Hashim for the first time at his home 6 years back when he invited Ali for lunch and Ali tagged me along. Hashim was only 11 years old then which makes him 5 years younger than me. After getting done with our meals, we rested in couch while Hashim connected his laptop to internet. After signing in to Windows Live Messenger, he called out to me, ‘Hey, give me your email address so I can add you to my friends’ list and we can chat online sometimes’. This came as a shock for me as I wasn’t expecting him to be so fluent at English, especially at such young age, that he was capable of chatting online in this language. I still had to hear it from him once so I confirmed and received his confident reply, ‘Yes, I can speak in English fluently’. ... Soon I was able to realize that he belongs to an extremely rich family who must have spent massive amounts of money on his education. Nevertheless, that moment I promised myself that I shall work on my English language and soon be a fluent at writing, speaking and understanding it. To enable this, the very next day I joined a language institute to improve my English and enhanced my fluency within few days. This was a turning stone for my life and career: I got accepted at King Fahd University of Petroleum and Minerals, one of the best reputable universities in gulf countries. Additionally, the first year was a probation year where we had to go through extensive testing, including two English courses where the mentors were native English speakers. This also gave me an edge to get a better grip on American as well as British English language, terminologies and accent and distinctions between them. Due to my strong skills in the language, I was easily able to survive the first year with excellent grades. Concluding remarks Owing to my embarrassing moment triggered by Hashim’s question, not only did I get an aim and direction in life to be determined about, I also became part of a prestigious educational institution, built a strong career and have excellent communication skills in English language as of today. This was a crucial milestone in my life which modified my beliefs and attitude towards literacy. I became more mature and responsible and developed respect for educational concerns. Moreover, I started helping people in my vicinity to overcome their communication problems so they do not have to face similar embarrassing situation
