Specific Heat of a Metal Post-Lab I. Purpose The purpose of this lab is to determine the specific heat of an unknown metal. II. Safety Wear goggles and lab apron at all times. Use caution when boiling water. Do not pick up hot beaker or hot metal with hands. Use tongs. III. Pre-Lab Questions 1. A 12.5 g metal is raised to 100C in boiling water. It is put into 82.8 g of water at 22.4C‚ and the water rises to 28.6C. Recalling that the specific heat of water is 4.18J/gC‚ use the equation above

7/16/12 Heat of Fusion Heat of Fusion for Ice Introduction: This lab report is a step by step process in calculating the heat of fusion for ice and to compare the differences between salt added to room temperature water and salt added to icy water. To calculate heat of fusion‚ one must understand heat of fusion. Heat of fusion is the amount of heat required to convert a mass of a solid at its melting point into a liquid without an increase in temperature. As difficult as this may sound‚

In this lab‚ we will measure the heat of combustion‚ or calorimetry‚ of a candle and compare the found quantity with known values for other hydrocarbons. The calorific value is the total thermal energy released when a substance goes through complete combustion with oxygen. In order to achieve the purpose of this lab‚ we must first determine the mass of the tea candle. Then‚ we will determine our room temperature‚ measure about 100 mL of chilled water‚ and then pour the water into the given empty

Research Summary Heat stroke is defined by Knochel and Ouchama (2002‚ p. 1978) as “a core body temperature that rises above 40°C (105°F) and that is accompanied by hot‚ dry skin and central nervous system abnormalities such as delirium‚ convulsions‚ or coma.” Heat stroke can be the result of either exposure to a high environmental temperature or from an elevated core temperature due to strenuous exercise. However‚ due to the presentation of an ‘unconscious unknown’ the diagnosis of heat stroke can be

Swine Heat Stress ABSTRACT The purpose of this research project is to identify the effects of heat stress on swine. Heat stress is physiological distress caused by excessive temperatures usually over 80-85 degrees Fahrenheit that can result in profoundly adverse effects in swine production. The first phase of this project involves the analysis of these harmful effects on sows‚ gilts‚ and boars. Multiple journal articles will be used to establish these effects. The final phase involves

August Heat Suspense can make you over think and become attentive. The feeling of wanting to know more creates confusions and boldness to the reader. The reason for suspense is to hook the reader onto the story‚ while hooking the reader to the story‚ the author wants to astound the reader into wanting more. W.F Harvey introduces suspense and it is shown throughout the story “August Heat” but it’s enhanced in the ending of the story. The story is about two men who occasionally meet one hot summer
