Question
How will you demonstrate the dynamic nature of equilibrium state?
Solution
Take a vessel with a hole in it.

Plug the hole and fill it half with water from a water tap. Now remove the plug and simultaneously adjust the run in the tap so that the rates of out-flow and in-flow of water are equal. The level of water inside the vessel remains constant though water is flowing into and out of the vessel. This is a state of dynamic equilibrium.
