SUMMARY
The discussion centers on demonstrating that the latent heat (L) remains approximately constant during solid to liquid phase transitions at temperatures significantly lower than the critical temperature (Tc). The relevant equation involves the specific heat capacities (cp1 and cp2) and the volumetric thermal expansion coefficients (α1 and α2). A suggestion is made to utilize the Clapeyron equation to relate pressure and temperature changes along the solid-liquid equilibrium line, which is crucial for solving the differential equation presented.
