Write the equation used to determine the latent heat of fusion of ice in terms of the appropriate masses, temperature changes and specific heats (define all quantities) in an adiabatic process. Check the experiment for the items making up the system. Have the ice start off at 0°C. Keep the equation that you are writing in non-numerical terms. Starting at 0°C is telling you that you will have a term involving the latent heat of fusion and another term of warming to the equilibrium temperature. State in one sentence the basic principle of physics expressed by this equation.
