... To describe the Carnot cycle taking place between temperatures Tc and Th , we assume that the working substance is an ideal gas contained in a cylinder fitted with a movable piston at one end. The cylinder’s walls and the piston are thermally nonconducting. Four stages of the Carnot cycle are shown ...
