The change in entropy of the system, ΔSsys, undergoing a cyclic ...
Denoted as ΔS, is a measure of the disorder or randomness of the system. It is defined as the difference between the entropy of the final state (Sf) and the entropy of the initial state (Si). Mathematically, it can be expressed as:

ΔS = Sf - Si

Entropy is a thermodynamic property that quantifies the number of microstates corresponding to a given macrostate. It increases with an increase in the number of possible arrangements or configurations of the particles in the system.

The change in entropy can be positive, negative, or zero, depending on the process. If the system becomes more disordered, the change in entropy is positive. If the system becomes more ordered, the change in entropy is negative. If there is no change in the disorder of the system, the change in entropy is zero.

The change in entropy is related to the heat transfer (Q) and the temperature (T) of the system through the equation:

ΔS = Q/T

This equation is known as the Clausius inequality and is a statement of the second law of thermodynamics. It states that the change in entropy of a system is equal to the heat transferred to the system divided by the temperature at which the heat transfer occurs.

In summary, the change in entropy of a system is a measure of the disorder or randomness of the system and is related to the heat transfer and temperature of the system.
