Per NCERT §5.2.1, a process is called REVERSIBLE if it satisfies which condition?
AProceeds infinitely slowly through a series of equilibrium states such that an infinitesimal change in conditions can reverse it
BInvolves no heat
CCannot be reversed at all
DProceeds quickly
Answer & Solution
Correct answer: A. Proceeds infinitely slowly through a series of equilibrium states such that an infinitesimal change in conditions can reverse it
Per NCERT §5.2.1, reversible = infinitely slow + always near equilibrium with surroundings. All other processes are irreversible.
