Third Law

The second law of thermodynamics has introduced entropy, and this function has been shown to be important when directions of spontaneous changes are investigated. The second law, moreover, shows how differences in entropy of two states of a system can be determined. The third law gives a method for assigning a value to the entropy of a system.
The third law of thermodynamics also, like the first and the second laws, is an expression of our experience with nature. It has evolved from Nernst’s observations that at very low temperatures
the enthalpy and the free energy of a reaction approach each other asymptotically, that the asymptote is parallel to the temperature axis and just above absolute zero they virtually cease to vary with temperature. This behaviour is shown schematically in Figure 3.1 (A). Mathematically, the changes in the free energy and the enthalpy of a reaction in the vicinity of absolute zero are expresse as:
