When macro properties of a system do not change with time, the system is said to be in equilibrium.
(a) Mechanical Equilibrium – When no work is done by one part of the system on its other part, it is said to be in a state of mechanical equilibrium. Pressure remains constant throughout the system.
(b) Thermal Equilibrium – Temperature remains constant throughout the system. No transfer of heat takes place from one part of the system to the other.
(c) Chemical Equilibrium – In this, a composition of the system remains constant and definite.
