Question

A thermally insulated vessel contains some water at 00C. The vessel is connected to a vacuum pump to pump out water vapour. This results in some water getting frozen. It is given Latent heat of vaporization of water at 0 to the power of ring operator end exponent C equals 21 cross times 10 to the power of 5 end exponent J divided by k g and latent heat of freezing of water equals 3.36 cross times 10 to the power of 5 end exponent J divided by k g. The maximum percentage amount of water that will be solidified in this manner will be

  1. 86.2%    
  2. 33.6%    
  3. 21%    
  4. 24.36%    

The correct answer is: 86.2%
