उत्तर
- Entropy is a thermodynamic state function that is a measure of the randomness or disorderliness of the system.
- For a reversible change taking place at a constant temperature (T). the change in entropy
- The system is equal to heat energy absorbed or evolved (q) by the system divided by the constant temperature (T).
`Δ"S"_"sys" = "q"_"rev"/"T"`
