100 gram of ice at 0oC is located into 100 gram of warm water in an insulated container. The initial temperature of the warm water before the ice is added is 40oC. Answer the following questions pertaining to the system after it arrives at thermal equilibrium.
(A) Determine the final temperature of the system?
(B) Find how much heat flowed from the warm water in the approach to equilibrium?
(C) Determine the mass of the ice that remains when equilibrium is achieved?
(D) Determine the net change in entropy between the initial and final states of the system?
