The equation of state for an ideal or perfect gas is the ideal gas law and reads. where P is the pressure, V is the volume, n is amount of gas (in mol units), R is the universal gas constant, 8.314 J/(mol K), and T is the temperature.
Since 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.
