Entropy change

  1. Aug 27, 2009 #1
    1. The problem statement, all variables and given/known data

    Find the change in the entropy of 250 g of liquid water at its boiling point when it is
    vaporised at a pressure of 8 atm. Give a brief physical explanation for how this entropy
    change compares with the entropy change for vaporisation at 1 atm pressure

    2. Relevant equations



    3. The attempt at a solution

    I was just thinking of dividing the latent heat of transformation by the temp in kelvin. But I don't know what the pyhsical explanation

    How does the entropy of liquid water compare at 1 vs. 8 atm? How about a gas? Which do you think would be the bigger difference and why?
