# Energy Required to Vaporize Methanol

I apologize for the fact that I am a complete layman. It might be time for me to go and learn some thermodynamics.

I am working on the design for a production lab at my Community College, and while I'm sure we have engineers to do this for us, I was really curious about sizing a boiler. I will not be heating methanol alone, I think if I can understand the process, then I can do the rest.

I do believe there are 2 terms in the problem.

Q=CP (kJ/kg) * m *$$\Delta$$T + Latent heat of Vaporization (kJ/kG)*m

Am I missing anything here? My question is, how do I account for that fact that the CP changes with the temperature of the medium? I have a background in Calculus and Diff Eq, with one semester of Physics (Calculus based mechanics), I'm just not sure what to do here.

Here are a couple of links for methanol properties:
