From thermodynamics the entropy difference perunit volume between the normal and superconductingstates isSV 00T a B22m0b where B 2/20 is the magnetic energy density neededto return a superconductor to the normal state. Usethis fact to compute the entropy difference betweenthe normal and superconducting states in 1 mole ofniobium at a temperature of 6.0 K.
