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 x 10^{6 } Jkg^{–1} and Latent heat of fusion of water = 3.36 x 10^{5} J kg^{–1} )

(1) 130 g (2) 35 g (3) 150 g (4) 20 g
