The entropy of an adiabatic isolated system can never increa

The entropy of an adiabatic (isolated) system can never increase? True or False? Explain.

Solution

Solution :

The entropy of an isolated system can never increase is false.

The reason is given by the second law of thermodyanmics which states that the entropy of the isolated system can never decrease beause it always evolves towards thermodynamic equilibrium which is a state of maximum entropy.
