FAQ

What is the Vapour Pressure?
The Vapour Pressure is the pressure exerted by a vapor in equilibrium with its liquid or solid phase at a given temperature. Vapour Pressure is usually measured using the Pascal for Pressure. Note that the value of Vapour Pressure is always negative.
Can the Vapour Pressure be negative?
Yes, the Vapour Pressure, measured in Pressure can be negative.
What unit is used to measure Vapour Pressure?
Vapour Pressure is usually measured using the Pascal[Pa] for Pressure. Kilopascal[Pa], Bar[Pa], Pound Per Square Inch[Pa] are the few other units in which Vapour Pressure can be measured.
