Academics

A Piece of ice of mass mi at 0 C is placed in water of mass mw at 20 C. The system is in a container of negligible heat capacity and insulated from its surroundings.

A) What is the ratio of the mass of the ice to the mass of water required for all the ice to melt?

B) What is the equilibrium temperature of the system?

C) If the ratio of the mass is 0.5(mw=2mi), what fraction of the ice melts?
