A thermally insulted vessel contains 150 g of water at\[0{}^\circ C\]. Then the air from the vessel is pumped out adiabatically. A fraction of water turns into ice and the rest evaporates at \[0{}^\circ C\] itself. The mass (in gram) of evaporated water will be close to : (Latent heat of vaporization of water\[=2.10\times {{10}^{6\,}}\,J\,k{{g}^{-1}}\]and Latent heat of fusion of water\[=3.36\times {{10}^{5\,}}\,J\,k{{g}^{-1}})\]
