Explain the molar heat of vaporization of water


Determine the values of delta H, delta U, and delta S for the following process:

At 25 degrees Celsius and 1atm 1 mole of liquid water ----> 1 mole of steam at 100 degrees Celsius and 1 atm.

The molar heat capacity of water is 75.3 J /K.mol and the molar heat of vaporization of water at 373 K is 40.79 kJ /mol. Assume the molar heat capacity to be temperature independent and ideal gas behavior.
