What is entropy?
Entropy is a thermodynamic state function that measures the degree of randomness or disorder in a system.
It is denoted by the symbol $S$.
For a reversible process,the change in entropy $(dS)$ is defined as the ratio of heat absorbed reversibly $(dq_{rev})$ to the absolute temperature $(T)$:
$dS = \frac{dq_{rev}}{T}$.
The unit of entropy is $J \ K^{-1} \ mol^{-1}$.
