... The difference between E and H is the amount of expansion work (P V work) that the system can do. Unless there is a change in the number of moles of gas present, this difference is extremely small and can usually be neglected. For an ideal gas, PV = nRT. At constant temperature and pressure, P ...

The kinetic theory of the gases
... As an application of the expression above for the equation of state, let’s consider an adiabatic process, one in which the gas container is thermally well isolated, i.e. no heat-transfer occurs. No heat-transfer is added or removed to the gas, Q = 0 As the piston is pressed, work is done on the gas ...
