1. When a system executes a cyclic process, network transfer is equal to net heat transfer. |
2. It is impossible to construct an engine, that operating in a cycle will produce no other effect than the extraction of heat from a reservoir and performance of an equivalent amount of work. |
3. It is impossible by any procedure, no matter how idealized, to reduce any system the absolute zero of temperature in a finite number of operations |
4. It is impossible to construct a device that operating in a cycle will produce no effect other than transfer of heat from a cooler to hotter body. |
