Read the above assertion and reason and choose the correct option regarding it.

Which of the following statement(s) is are correct?

Statement (i): The entropy isolated system with P-V work only, is always a maximized at equilibrium.

Statement (ii): It is possible for the entropy of a close system to decrease substantially in an irreversible process.

Statement (iii): Entropy can be created but not destroyed.

Statement (iv):

Δ S_{s y s t e m}

is zero for reversible process in an isolated system

Q. For an isolated system, the entropy:

In an isothermal process system is in contact with outside heat reservior and the change occur slowly so as to facilitate to adjust temp and in adiabatic process system is isolated. Then my question is even if adiabatic system is isolated then how the temperature changes.
