The chief practical value of a Maxwell relation is that it

  • A.makes an equation of state entirely unnecessary
  • B.replaces an entropy derivative with a measurable one
  • C.gives the numerical value of the entropy quite directly
  • D.removes any need at all for heat capacity data

Answer: B

Entropy cannot be measured directly, but pressure, volume and temperature can, so a relation converting one into the other is exactly what a property calculation needs. Heat capacity data are still required for the temperature dependence.
