Entropy Formula
Randomness of any system is called entropy of system.
- Entropy is also a thermodynamic quantity which depends on thermodynamic variable that is temperature , pressure or volume.
- We can not calculate the absolute value for entropy of any system.
- But we can calculate change in entropy.
∆S = S2 – S1
∆S = Change in entropy
S1. = initial entropy of system
S2. = Final entropy of system
Formula of entropy:
∆S = entropy
qres = heat exchange for the system for reversible
T =. Temperature (Kelvin)
- Unit of entropy joule/k
