A student is trying to determine the heat capacity of a substance at constant pressure, given its thermodynamic properties. The substance is in the gas phase and is confined to a container at a specific temperature and pressure. What is the mathematical expression for the heat capacity of the substance in terms of its thermodynamic properties, and what is the numerical value of the heat capacity at the given temperature and pressure? How would the heat capacity change if the temperature or pressure were to be changed?
