Third Law of Thermodynamics

The third law of thermodynamics simply states that it is not possible to reach a temperature of absolute zero. It is possible to come arbitrarily close to absolute zero but not possible to reach that temperature by any process or series of processes.

If a temperature of absolute zero is impossible, then it is not possible for a Carnot cycle engine to reach 100% efficiency. The third law of thermodynamics therefore closes the loophole that the Carnot cycle opens in the second law of thermodynamics.
