Enthalpy of Vaporization

Postby JukaKim_1D » Thu Feb 04, 2016 3:21 pm

What is the significance of the enthalpy of vaporization of water at 25C? Does this mean that the water undergoes a phase change from liquid to gas at 25C? How is that possible?

This is the process where you let the water heat to the vaporizing temperature (100 C), let it vaporize at that temperature, and then let it cool back down to the initial temperature (25 C). Water cannot normally vaporize at 25C, we have to use this special process to calculate the value of it.
