Two identical containers are separated by a thin metal partition as shown in Figure Both containers are well insulated from the surroundings and contain 1.00 kg of water. The initial temperatures of the water are 100°C and 0°C before reaching a final equilibrium temperature. The thin metal partition has negligible mass. Thermal insulator Water at Water at 100 °C 0°C thin metal partition with negligible mass Figure (a) Is this process reversible or irreversible? Justify your answer. (b) Determine the total change in entropy for the whole system.
