second law of thermodynamics

Question

According to the second law of thermodynamics, in an isolated system:

RankGuru · Accepted Answer

The **Second Law of Thermodynamics** states that the total entropy of an isolated system (which does not exchange matter or energy with surroundings) can never decrease over time.
- For a spontaneous process in an isolated system, the change in entropy is always positive: $\Delta S_{sys} > 0$.
- The system will evolve towards a state of maximum entropy, which corresponds to thermodynamic equilibrium.
- $\Delta S_{universe} = \Delta S_{sys} + \Delta S_{surr} \ge 0$.
