Very Few Thermodynamics Under Graduate Students Have Passed

Very Few Thermodynamics Under Graduate Students Have Passed.
This sentense has something to do with a pnemonic technique. An under-graduate student might get some worries reading that in a book of thermodynamics, but the interesting fact about this sentence is that first letter of every work stands for one of symbols of following crucial quantities which are always related to each other and describe the various equations of state.

Volume
F ( Helmholtz potential)
Temperature
Internal Energy
Gibb's free energy
Entropy
Enthalpy
Pressure.

One of the best pnemonic technique I have seen so far :)
Maxwell relations can be derived from the square- coming soon.
