Title: Specific Heat of Solids II. Object: To determine the specific heat capacity of solids by methods of mixtures. III. Theory: When to or more substances at different temperatures are mixed‚ heat will flow from the substance of higher temperature to the substance of lower temperature. The heat flow will continue until equilibrium in temperature is reached. From the Law of Conservation of Energy‚ whatever amount of heat is lost by the hot substance must be equal to the heat gained by the cold

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‚

overall heat transfer coefficient on the outer surface of the covered pipe is 10 W/m2.K. if the velocity of the steam is 10 m/s‚ at what point along the pipe will the steam begin condensing and what distance will be required for the steam to reach a mean temperature of 100 oC? Question 2: Consider a horizontal‚ thin walled circular tube of diameter D = 0.025 m submerge in a container of n-octadecane (paraffin)‚ which is used to store thermal energy. As hot water flows through the tube‚ heat is

cheerleader bugs the “odd girl”‚ as for example in “Mean Girls”. The most prominent contrast in the film is the home of the MacGuffs VS. the home of the adoptive parents Mark and Vanessa Loring. The two homes are set like two different worlds. In the MacGuff house‚ it seems like it is impossible to have too many lamps‚ ornamental dogs or photo frames. The color scale goes in earthy brown tones. Meanwhile‚ the Loring house does not seem to ever be perfect enough. As Vanessa and Mark are introduced

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

Paper Color in Cabaret In the movie Cabaret color is used to symbolize many different things. There is a wide array of color that shows the viewer what is going on between the characters and what the general emotion of a scene is. In many instances the colors foreshadow what will happen later in the movie. Conflicts in the film are also shown by the difference in color schemes making it more obvious to the viewer the contrast of the two ideals in conflict. This masterful use of color is

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
