Description: Shows how a large air-filled cylinder is closed with a heavy piston and when the piston is displaced from equilibrium the system oscillates. Explains two conditions for long oscillations (reversibility) - when the surface area approaches zero, the temperature changes in the gas are high (adiabatic,) and when the surface area becomes very large, there are no measurable temperature changes (isothermal.).
