The third law of thermodynamics states that the entropy of a system at absolute zero is a well-defined constant. This is because a system at zero temperature exists in its ground state , so that its entropy is determined only by the degeneracy of the ground state.

The laws of thermodynamics provide an elegant mathematical expression of some empirically-discovered facts of nature. The principle of energy conservation allows the energy requirements for processes to be calculated. The principle of increasing entropy (and the resulting free-energy minimization) allows predictions to be made of the extent to which those processes may proceed. Thermodynamics

The Third Law of Thermodynamics gathers several important observations on the behavior of systems at very low temperature into a single general rule. The observations include the following. 1. The most striking outcome of low-temperature experiments is the failure to achieve the absolute zero of temperature. While low-temperature physicists are constantly setting new records for minimum

THIRD LAW OF THERMODYNAMICS:-In all heat engines, there is always loss of heat in the form of conduction, radiation and friction. Therefore, in actual heat engines Q 1 /T 1 is not equal to Q 2 /T 2. Thus, Q 1 /T 1 – Q 2 /T 2 is not zero but it is a positive quantity. When cycle after cycle is repeated, the en . tropy of the system increases and tends to a maximum value. When the system has

The Nernst postulate (third law of thermodynamics) puts a lower bound on entropy, which is a consequence of the quantum laws of nature. This chapter discusses the thermodynamic consequences of the Nernst postulate.
