Maxwell relations

Maxwell's relations are a set of equations in Thermodynamics which are derivable from the definitions of the four thermodynamic potentials. They involve the following quantities:

V is volume
T is temperature
P is pressure
S is entropy
The equations u refer from books.
A mnemonic used by physics students to remember the Maxwell relations in thermodynamics is "Good Physicists Have Studied Under Very Fine Teachers", which helps them remember the order of the variables in the square, in clockwise direction. Another mnemonic used here is "Valid Facts and Theoretical Understanding Generate Solutions to Hard Problems", which gives the letter in the normal left to right writing direction.
