Chemists use this word all the time apparently. And I have known some chemists! Why didn't they tell me?
The word dates back to 1909.
The word enthalpy is based on the Greek word enthalpos (ἔνθαλπος), which means to put heat into.And the word gets used a lot in discussions of heating up chemicals.
This is to be sung to the tune of McCartney's "Ebony and Ivory":
Entropy and enthalpy
are both thermodynamic properties
having something to do with energy
