PRE-LAB FORM LATENT HEAT AND SPECIFIC HEAT 1. What is your explanation of heat? 2. What is a calorimeter? 3. Define the specific heat. 4. Define the latent heat of fusion and the latent heat of vaporization. 5. In an experiment 70 gram of ice at 0 °C is dropped into 300 gram of water at 50 °C. Assuming that the calorimeter prevents heat flow to the surroundings, what is the final temperature of thermal equilibrium? (Ignore the calorimeter.)
The Latent Heat of Vaporization for water is L-540 cal/g 2.26x10 J/kg. If 300 g of water went from room temperature, 220C, to 50°C in the calorimeter, how much steam (expressed in grams) would be produced? Briefly describe the physical phenomena that are involved in this process.

1. (8 pts) Virtually every pchem textbook has a table of enthalpy values for 25°C. One use for these may be to calculate the enthalpy fora phase change such as boiling. However, not t0o many compounds boil at 25°C. You are going to calculate the percent difference between the heat of vaporization of ethanol using data for 25°C and that at its boiling point of 78°C. a) Write the chemical equation that shows the vaporization of 1 mol of ethanol...
