I hope you're up on your calculus:

That should keep you busy for awhile.

Enthalpy is not a mathematical concept, it is a physics/chemistry concept. If U is the total energy,p is the pressure and V is the volume, then the enthalpy H=U+pV.

Enthalpy is heat in a chemical reaction. There will be a gain or loss and that would be written as delta H. delta means change and H is enthalpy.
You should be aware that you never know the total amount of enthalpy in any system. You only get to know the change in H that you have released or absorbed.

H = U + PV :
H=enthalpy, U=internal energy, P=sys. pressure, V= volume

It's purely a chemical thing. Some communists know that.
