Anyone know a good mnemonic device for all the state variables we need to know?

PDTVHUGS, Pressure(P) Density(D) Temperature(T) Volume(V) Enthalpy(H) InternalEnergy(U) GibbsFreeEnergy(G) Entropy(S)

I think Lyndon's went something like this:
If you're under Pressure and Depressed, just watch some TV and get lots of HUGS.

What is this telling us? Is it showing a relationship between them or just showing what each of the variables represents?

Its just saying that all of those are state variables.
