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