What is the maximum work that can be obtained from a periodically operating heat engine, the heater of which is m1 = 1 kg of water at an initial temperature T1 = 373 K, and the refrigerator m2 = 1 kg of ice at a temperature T2 = 273 K, by the time all the ice has melted? What will be the temperature of the water at this moment? Specific heat of melting of ice q = 335 J/g. Neglect the dependence of the heat capacity of water on temperature.
