... The Entropy of an isolated system never decreases. It is impossible for heat to (spontaneously) flow from a cold to a hot object. It is impossible for a heat engine working in a cycle to absorb heat and perform an equal amount of work. The most efficient heat engine operating between two given tempe ...
