The third law of thermodynamics deals with the entropies of the perfect crystalline substances
at absolute zero of temperature.
According to third law of thermodynamics, at absolute zero, the entropy of a perfectly
crystalline substance is taken as zero.
This law was first formulated by Nernst in 1906. Since entropy is related to disorder, according
to third law, at absolute zero, there is least disorder or there is perfect order. Therefore, the
entropy at perfect order is taken as zero.
It may be noted that this law is true only for those substances which exist in the perfectly
crystalline form at 0 K. However, if there are imperfections of any type in the perfect crystalline
arrangement at 0 K, then the entropy will be larger than zero.
Explanation :
In simple terms, the third law states that the entropy of a perfect crystal approaches zero as
the absolute temperature approaches zero. This law provides an absolute reference point for
the determination of entropy.
