Question

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.)
