SUMMARY
The discussion focuses on calculating the temperature and pressure of a melting point using thermodynamic principles. Participants emphasize the importance of the derivative of pressure (P) with respect to temperature (T) at constant entropy (s) and the slope of the fusion curve, particularly noting that at 1 atm, the fusion curve intersects at 0°C. The consensus is to assume that the partial derivative of P with respect to T remains constant throughout the process to accurately plot the graph of P versus T for the solid phase.
