Applications of Third Law of Thermodynamics
The applications of the Third Law of Thermodynamics include:
- The calculation of absolute entropy, which is essential for determining the thermodynamic properties of substances.
- The understanding of the behavior of heat capacities as the temperature approaches zero.
- The realization that absolute zero cannot be reached, and that it is the lowest possible temperature.
- The development of atomic standards, such as atomic clocks, which use laser-cooled atoms at low temperatures
- The study of quantum effects in solids and liquids with temperatures close to absolute zero.
Third Law of Thermodynamics
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. The principle gives us insight into the behavior of matter at low temperatures which is of huge importance for various branches such as physics, chemistry, and materials science.
In this article, we will learn about third law of thermodynamics along with its application and limitations.
