An ideal refrigerating engine operating according to Carnot cycle transfers heat from a cold reservoir filled with water with a temperature of 0 °C to a hot reservoir filled with water with temperature of 100 °C. How much water needs to freeze in the cold reservoir, so that 1 kg of water in the hot reservoir evaporates and the temperature of the vapour is 100 °C?
