Maxwell relation

Show Summary Details

Quick Reference

A set of relations in thermodynamics:

TV)S = (δPS)V,

TP)S = (δVS)P,

PT)V = (δSV)T,

VT)P = −(δSP)T,

where T is the absolute temperature, V is the volume, P is the pressure, and S is the entropy. The Maxwell relations are useful for converting quantities that cannot readily be measured into quantities that can.
