SECOND LAW OF THERMODYNAMICS

Clausius statement Heat can flow spontaneously from a hot object to a cold object; heat will not flow spontaneously from a cold object to a hot object. A refrigerator requires work

Kelvin-Planck statement No device is possible whose sole effect is to transform a given amount of heat completely into work. No engine can be 100% efficient

general statement The total entropy of any system plus that of its environment increases as a result of any natural process. The total entropy of an isolated system that undergoes a change cannot decrease.
