Test: Thermodynamic Relations - 2 - Question 5

Gibb’s free-energy functions is a property comprises

Detailed Solution for Test: Thermodynamic Relations - 2 - Question 5

Gibbs free energy function (G)
G = H - TS = f(H, T, S)

Test: Thermodynamic Relations - 2 - Question 6

 The specific heat at constant pressure (Cp) is given by

Detailed Solution for Test: Thermodynamic Relations - 2 - Question 6

From TdS equation
TdS = dh - VdP
for constant pressure process
dP= 0
Since dh = cpdT
TdS = CpdT
