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. WebBy manipulating pressure, chemists can force chemical reactions to occur and the transitions between solids, liquids, and gases to accelerate. However, these pressure manipulations are on a small scale, not differing that much from the atmospheric pressure we experience everyday.

The atmospheric pressure is directly proportional to the boiling point of a liquid. When a liquid is trying to escape into a gaseous state, the atmospheric pressure limits its ability to break away by putting pressure on it. The vapour pressure is defined as the pressure exerted by the vapours above the liquid.
