Vapor pressure[a] or equilibrium vapor pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature …

Apr 24, 2021 · Vapor pressure (or vapour pressure) is the equilibrium pressure of a vapor above its liquid or solid state in a closed container. In this type of closed system, some molecules of a …

The vapor pressure of a liquid is the equilibrium pressure of a vapor above its liquid (or solid); that is, the pressure of the vapor resulting from evaporation of a liquid (or solid) above a sample of …

Vapor pressure is the pressure exerted by a gas when it is in equilibrium with its liquid or solid form. In a closed container, some molecules of a liquid always escape into the air as gas, …

Jan 30, 2023 · The vapor pressure of a substance is the pressure that the gaseous part of the substance exerts on the container of said substance. The fact that the vapor pressure is equal …

For water, the vapor pressure reaches the standard sea level atmospheric pressure of 760 mmHg at 100°C.

Sep 17, 2025 · Vapour pressure, pressure exerted by a vapour when the vapour is in equilibrium with the liquid or solid form, or both, of the same substance—i.e., when conditions are such …

Oct 17, 2014 · Vapor and saturation pressure for some common liquids. The vapor pressure of a liquid is defined as the pressure exerted by the molecules that escapes from the liquid to form …

Vapor pressure is a measure of how eagerly molecules escape from a liquid (or solid) into the gas phase. When evaporation and condensation balance out, the vapor pressure represents a …

Vapor pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases. It represents the tendency of molecules in a substance to escape into the …
