A thermally isolated vessel contains 100 g of water at 0∘C. When air above the water is pumped out, some of the water freezes and some evaporates at 0∘C itself. Calculate the mass of the ice formed if no water is left in the vessel. Latent heat of vaporization of water at 0∘C = 2.10 × 105 J kg−1 and latent heat of fusion of ice = 3.36 × 105 J kg−1 |
