\(\oint \frac{{dQ}}{T}\), represents entropy in a cyclic process.
Generally, \(\frac{{\partial Q}}{T} = {\rm{dS}}\)
and \(\oint \frac{{\partial Q}}{T}\) represents a cyclic integration of S and represented as \(\oint dS\)
\(\oint \frac{{\partial Q}}{T} \le \oint dS\) for any cycle.
Additional Information
As per Clausius Inequality
If \(\oint \frac{{\partial Q}}{T} = 0\) the cycle is reversible.
If \(\oint \frac{{\partial Q}}{T} < 0\) the cycle is irreversible.
If \(\oint \frac{{\partial Q}}{T} > 0\) the cycle is impossible.
Since entropy is a property, the cyclic integral of any property is zero
\(\oint \frac{{\partial Q}}{T} \le 0\)
