To what height could a 100 kg load be raised if it were possible to completely convert the energy released when a glass of water is cooled from 100°C to 20°C into work? The mass of water in a glass is 250 g, the specific heat capacity of water is 4200 J/(kg*K), the heat capacity of the glass is not taken into account, g = 10 m/s2.
