Class 11 Third law of thermodynamics (brief introduction)- The third law of thermodynamics is one of the fundamental principles in the field of thermodynamics, which is the study of energy and its transformations. This law is also known as the “law of absolute zero” or the “Nernst heat theorem.” It was formulated by German chemist and physicist Walther Nernst in the early 20th century.
The third law of thermodynamics states that as the temperature of a system approaches absolute zero (0 Kelvin or -273.15 degrees Celsius), the entropy of the system approaches a minimum or constant value. In simpler terms, it implies that it is impossible to reach absolute zero in a finite number of steps.
Absolute zero is the lowest possible temperature at which a system possesses minimal thermal motion and energy. The third law provides insight into the behavior of matter at extremely low temperatures and the theoretical limits of cooling processes.
One important consequence of the third law is the determination of the absolute entropy of a substance at any temperature above absolute zero. It is often used to calculate the entropy changes in various processes, particularly in the field of chemical thermodynamics.
In summary, the third law of thermodynamics establishes the unattainability of absolute zero temperature and provides a framework for understanding the behavior of systems as they approach this theoretical limit.
