Consider a system that undergoes a phase change from phase a to phase b at equilibrium temperature T and equilibrium pressure p. At these equilibrium conditions, the heat absorbed per mole of material undergoing this transition is q, and there is a molar volume change of V,_m. The molar heat capacities for the and phases are Cp,_m, and Cp,_m,; they are independent of temperature.

A.) Write a thermodynamic cycle that would allow you to calculate the equilibrium transition temperature corresponding to a pressure of 1000 bar. Use the cycle to write an equation that could in principle be solved to calculate T at 1000 bar.
