Entropy (Cont’d)<br />
Note that entropy is a property. It has fixed values<br />
at fixed states.<br />
The entropy change ΔS between two specified<br />
states is the same no matter what path,<br />
reversible or irreversible, is followed during a<br />
process.<br />
From definition of entropy:<br />
Also note that the integral of δQ/T will give us the<br />
value of entropy change only if the integration is<br />
carried out along an internally reversible path<br />
between the two states.<br />
