SUMMARY
The discussion focuses on the impact of surface tension on thermodynamic potentials in soap bubbles, specifically through the differential work expression dW = −pdV + γdA. Participants explore how to derive new differential expressions for the internal energy (U), enthalpy (H), Helmholtz free energy (F), and Gibbs free energy (G), while identifying the natural variables associated with each potential. Additionally, the conversation touches on the potential existence of new Maxwell relations arising from these modifications.
