Question

24. Derive

av=1/t



for ideal gas.

Answer 1

Welocome friend,

● Explaination -
According to ideal gas equation -
PV = RT

Taking limiting values,
PdV = RdT
dV/dT = R/P

From Gibbs free energy, αv is given by -
αv = 1/V (dV/dT)
αv = 1/V (R/P)
αv = R / PV
αv = R / RT
αv = 1/T

Therefore, for ideal gas αv = 1/T.

Hope this helps you...
