Question

A thermally insulted vessel contains 150 g of water at 0º C . Then the air from the vessel is pumped out a adiabatically. A fraction of water turns into ice and the rest evaporates at 0º C itself. The mass of evaporated water will be closes to:
(Latent heat of vaporization of water = 2.10 × 10⁶ Jkg⁻¹ and Laten heat of Fusion of water = 3.36 × 10⁵ Jkg⁻¹)
(A) 35 g (B) 150 g
(C) 130 g (D) 20 g
