Question

A sample of ice and a 0.560 kg sample of liquid water are placed in a thermally isolated container. The container also contains a device that is designed to regulate the transfer of heat energy (from the liquid water to the ice) so that it occurs at a constant rate P, until thermal equilibrium is reached. The temperatures T of the liquid water and the ice are given in the figure below as functions of time t.

(a) What is magnitude of the rate P? (Answer a +.)
  ??? W
(b) What is the initial mass of the ice in the container?
??? kg
(c) When thermal equilibrium is reached, what is the mass of the ice produced in this process?
??? kg
