WebJan 27, 2024 · Specific heat capacity $\ce{C_p}$ can be used to calculate the enthalpy change even for the processes that are not at constant pressure as enthalpy is a state function, that is, it doesn't matter by which process you reach the end state, the value of enthalpy change will remain the same. Same is the case when we measure the change … WebHeat capacity or thermal capacity is a physical property of matter, defined as the amount of heat to be supplied to an object to produce a unit change in its temperature. [1] The SI unit of heat capacity is joule per kelvin (J/K). Heat capacity is an extensive property.

WebSince R is a constant and u = u (T), it follows that the enthalpy of an ideal gas is also a function of temperature only. h = h (T) Since u and h depend only on the temperature for an ideal gas, the constant volume and constant pressure specific heats c v and c p also depend on the temperature only. c v = c v (T) c P = c P (T)
