1. The problem statement, all variables and given/known data A plastic ice tray has a section filled with water. When placed in a coler, the water freezes into ice cubes. The mass of water is 320g and the initial temperature of water is 0 degrees Celsius. The specific latent heat of fusion is 330J/g. Pipes containing fluids are used to take away heat from the cooler. A)calculate the amount of heat required to freeze the water. B)state why the heat capacity of the plastic tray does not affect the answer to A). 2. Relevant equations Q=ml 3. The attempt at a solution A)320x330=105600J B) is the part that I'm more concerned with. The answer was that the temperature of the plastic tray and the water remains the same. Hence no heat is absorbed by the plastic tray and the heat capacity does not affect the answer in A). I don't understand this. Could someone explain this to me? Thanks for the help!
