A thermally insulated vessel contains 150 g of water at 0°C. Then the air from the vessel is pumped out adiabatically. A fraction of water turns into ice and the rest evaporates at 0°C itself. The mass of evaporated water will be closest to – (Latent heat of vaporization of water = 2.10 × 10 6 Jkg –1 and Latent heat of fusion of water = 3.36 × 10 5 J kg –1 )
