2. What does the water equivalent of the calorimeter represent? 3. Set up the expressions for the heat lost and the heat gained, and subsequently derive (4). 4. Before the ice is placed in the calorimeter, the ice is dried. Why did it need to be dry? If the ice was not dry, would the experimental value of the latent heat of fusion be higher or lower than the expected value? Explain. 5. If ice cubes are taken from a freezer and used immediately in the experiment, then will the value of the latent heat of fusion be less than or greater than the theoretical value? Explain
