What is the unit of the physical quantity Entropy?
- Awatt per kelvin
- Bnewton per kelvin
- Cpascal per kelvin
- Djoule per kelvin
Solution & Step-by-step Explanation
Entropy (S) is defined thermodynamically as ΔS=
T
ΔQ
, where ΔQ is the heat energy transferred (measured in Joules) and T is the absolute temperature (measured in Kelvin). Therefore, the SI unit of entropy is Joule per Kelvin (J/K).
