vapour pressure
Liquid's escape force
Vapour pressure is the pressure exerted by a gas in equilibrium with its liquid or solid form at a given temperature.
Higher temperatures increase vapour pressure as more molecules escape into the gas phase.
The concept explains phenomena like boiling points, evaporation rates, and humidity.
Also spelled vapor pressure in American English.
