Question

22
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 106 Jkg - and Latent heat of
Fusion of water = 3.36 x 105J kg-1)​
