A thermally insulated vessel contains 150g 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 × 10⁶ J kg^–1 and Latent heat of Fusion
of water = 3.36 × 10⁵ J kg^–1)
