Water can exist as ice, which is solid; it can exist as a liquid; or it can exist in the gaseous state as water vapour or steam. In this fifth unit of class 11 chemistry, we will learn more about these three physical states of matter, particularly liquid and gaseous states. We learn about intermolecular forces, gas laws, ideal gas equation, Dalton's law of partial pressure, real gases, Vanderwaal's equation, Liquifaction of gases, the vapour pressure in liquids, surface tension, and viscosity.
