Explanation:

The entropy of a system tells the state of the randomness of that system at a particular temperature.

F1 Visamber Singh Anil 11-05.21 D3

From the above equations, we can see that change in the entropy is associated with the transfer of heat δQ.

Important Points

  • Change in entropy is a property, which is also a point function hence an exact differential.
  • Entropy generation is not a property and it depends on the path through which the process occurs and hence an inexact differential.
