Third law of thermodynamics: The third law of

The third law of thermodynamics concerns the behavior of atoms and molecules at absolute zero temperature. It states that the entropy of a system is zero as the temperature approaches absolute zero. In other words, the entropy of a perfect crystal of a pure substance is zero at zero Kelvin (0 K) [1-4]. Third Law Of Thermodynamics What is the Third Law of Thermodynamics? The third law of thermodynamics states that the entropy of a perfect crys. al at a temperature of zero Kelvin (absolute zero) is equal to zero. Entropy, denoted by. Nonetheless, the combination of these two ideals constitutes the basis for the third law of thermodynamics: the entropy of any perfectly ordered, crystalline substance at absolute zero is zero. The entropy of a pure, perfect crystalline substance at 0 K is zero. Third law of thermodynamics, introduced in the late 19th century, is a fundamental concept in thermodynamics and statistical mechanics. This establishes a theoretical limit for absolute zero temperature, the lowest possible temperature where the particles undergo minimal vibrational motion.
