Query: Adiabatic reversible compression: a molecular view   The adiabatic compression (or expansion) of an ideal gas has been analysed.
Using the kinetic theory of gases the usual relation between temperature and
volume is obtained, while textbooks follow a thermodynamic approach. In this
way we show once again the agreement between a macroscopic view
(thermodynamics) and a microscopic one (kinetic theory).
