No,equilibrium is a state where macroscopic properties like pressure and volume remain constant over time.

Vedclass · Answer

(B) No,it is not necessary to change the volume and pressure to bring a system to equilibrium. In fact,the definition of thermodynamic equilibrium is that the macroscopic state variables of the system,such as pressure $(P)$,volume $(V)$,and temperature $(T)$,do not change with time. If a system is already in equilibrium,its pressure and volume are constant. If a system is not in equilibrium,it will naturally evolve over time until its properties (like $P$ and $V$) become constant,at which point it reaches equilibrium. Therefore,equilibrium is characterized by the constancy of these variables,not by the act of changing them.
