Class 12 Second Law of Thermodynamics

          Second Law Of Thermodynamics

This is the note of class 12 physics 2nd law of thermodynamics chapter,In this article we are going to provide thermondynamics chapter Note with some Important questions which was previously asked in NEB examination,

Introduction:

The Second Law of Thermodynamics is one of the most fundamental principles of thermodynamics, which states that the total entropy of an isolated system always tends to increase over time, or it remains constant in an idealized reversible process

Entropy is a measure of the degree of disorder or randomness of a system. According to the Second Law of Thermodynamics, the entropy of an isolated system cannot decrease over time, and the natural tendency is for the entropy to increase. This law can be expressed in various forms, such as the Clausius statement, which states that heat cannot spontaneously flow from a colder body to a hotter body.

In class 12 physics, the Second Law of Thermodynamics is an important topic as it is used to explain various phenomena, such as the efficiency of heat engines, the direction of spontaneous processes, and the limitations of energy conversion. Students are often introduced to the concept of entropy, the Carnot cycle, and the concept of irreversibility.

Overall, the Second Law of Thermodynamics is a fundamental principle of physics, and its understanding is essential for students of physics and engineering.
