Question

Can entropy be different for a system in the same state?

Answer 1

Since entropy is a state function, the entropy change of thesystem for an irreversible path is the same as for a reversible path between the same two states. ... In classical thermodynamics, theentropy of a system is definedonly if it is in thermodynamic equilibrium.

Answer 2

Explanation:

Since entropy is a state function, the entropy change of the system for an irreversible path is the same as for a reversible path between the same two states. However, the entropy change of the surroundings will be different.

SI unit: joules per kelvin (J⋅K−1)

In SI base units: kg⋅m2⋅s−2⋅K−1
