ice at 0.0 °C. How much energy (in Joules) must be supplied to the machine to achieve this task? So. Since the machine is a operating in a Carnot cycle, then, its efficiency is e = - | ITHỊ By virtue of first law, the work done to convert water to ice is given by W = Q = Thus, the total energy needed to convert 85 kg of water is ET = 687.5 J
