Equilibrium in Physical Processes

Equilibrium isn’t something that happens only in a beaker of chemicals — it’s all around you. When you leave a glass of water open, the water level slowly drops; if you seal it, the level stays constant. That constant level is a physical equilibrium: the rate of evaporation equals the rate of condensation, even though both processes continue. Understanding this dynamic balance in physical changes — like dissolution, vaporisation, and ph …
