The efficiency of the Carnot cycle exhibits a peculiarity in the thermal energy in its conversion of [heat→work], namely, the principle of increasing entropy. However, the Carnot cycle involves conversion both of [heat→work] and [work→heat], not merely conversion of [heat→work]. The definition of cycle efficiency does not satisfy the conservation of energy law. In this paper, we investigate whether the principle of entropy increase derived from the cycle describes a characteristic of the conversion of [heat→work].
