What is Vapour pressure?

Vapour pressure is the 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 that the substance can exist in both or in all three phases. It is a measure of the tendency of a material to change into the gaseous or vapour state, and it increases with temperature. The vapor pressure of any substance increases non-linearly with temperature. With any incremental increase in that temperature, the vapor pressure becomes sufficient to overcome atmospheric pressure and lift the liquid to form vapor bubbles inside the bulk of the substance and is measured in the standard units of pressure.

How to Calculate Vapour Pressure?

Vapour Pressure calculator uses Vapour Pressure of Solution = Mole Fraction of Solvent in Solution*Vapour Pressure of Solvent to calculate the Vapour Pressure of Solution, Vapour Pressure is the pressure of the vapor which is formed after a solid get dissolves into the liquid. Vapour Pressure of Solution is denoted by P_solution symbol.
