SUMMARY
The discussion focuses on proving that the thermal expansion coefficient β equals zero at absolute zero temperature (T = 0) using a Maxwell relation derived from Gibbs free energy. The relevant equations include the Gibbs free energy equation (G = U - TS + PV) and the definition of the thermal expansion coefficient (β = (1/V)(∂V/∂T) |_{N,P}). The participants conclude that the proof can be completed without relying on the ideal gas law, emphasizing the importance of the third law of thermodynamics in this context.
