WebApr 9, 2024 · The pressure exerted by the vapour (molecules in the vapour phase) over the surface of the liquid at the equilibrium at a given temperature is called the vapour pressure of the liquid. Vapour Pressure Illustration. The energy of the molecules increases when the liquid is heated, making them lighter and occupying the liquid’s surface. WebOsmotic pressure: The excess of pressure on the side of the solution, that stops the net flow of solvent into the solution through a semipermeable membrane is called osmoticpressure.

WebApr 6, 2024 · Osmotic pressure is the pressure applied to the solution to prevent osmosis. It is generally denoted by π. Osmotic pressure-a Colligative Property Van’t Hoff (1887) concluded that a dilute or ideal solution behaves like an ideal gas and the different gas laws are applicable to the dilute solutions as well. WebMay 6, 2024 · The boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure surrounding the liquid. Therefore, the boiling point of a liquid depends on atmospheric pressure. The boiling point becomes lower as the external pressure is reduced.
