Heat of fusion and vaporization

Postby JChen_2I » Tue Feb 11, 2020 12:37 am

Since heat of fusion for water is 6.01kJ/mol, is it correct that the change in enthalpy when going from liquid to solid be -6.01kJ/mol? And similarly going from gas to liquid would be -40.7kJ/mol?

I believe that's correct - heat of fusion is the enthalpy when something changes state from solid to liquid, so the sign would be switched for the heat of solidification (liquid to solid) but still the same magnitude.
