Understanding the thermodynamics’ fundamental are important for the advance of energy and environmental technologies. The study aims to derive an expression of the average pressure on the piston surface, pps in an adiabatic piston-cylinder system during an irreversible process with finite piston speed using the kinetic molecular theory. Expressions for the average pressure on the piston surface, pps are derived from the change of momentum and change of energy. The Maxwell-Boltzmann distribution is used to estimate the gas molecule velocities. The piston surface pressure obtained from the change of momentum is 37.18% lower than that obtained by the previous study. The piston surface pressure obtained from the change of energy is 26.94% lower than that obtained by the previous study.
