How Does Entropy Change When Vaporizing Water at Different Pressures?

[senan]

Homework Statement

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

Homework Equations

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?
