A container filled with 45 kg of liquid water at 95°C is placed in a 90-m3 room that is initially at 12°C. Thermal equilibrium is established after a while as a result of heat transfer between the water and the air in the room. Using constant specific heats, determine (a) The final equilibrium temperature, (b) The amount of heat transfer between the water and the air in the room, and (c) The entropy generation. Assume the room is well sealed and heavily insulated.
