A thermally insulated vessel contains some water at 0∘C. The vessel is connected to a vacuum pump to pump out water vapour. This results in some water getting frozen. It is given that the latent heat of vaporization of water at 0∘C is 21×105 J/kg and latent heat of freezing of water at 0∘C is 3.36×105 J/kg. The maximum percentage of water vapour that will be solidified in this manner will be - |
