Common Questions
Vapor pressure is the pressure exerted by a substance when it is in equilibrium with its vapor phase. It is a measure of the tendency of a substance to evaporate and turn into vapor. The vapor pressure of a substance depends on its temperature, molecular weight, and intermolecular forces. In a laboratory setting, vapor pressure is typically calculated using the Antoine equation, which takes into account the substance's temperature and molecular weight.
where Pv is the vapor pressure, A, B, and C are constants specific to the substance, and T is the temperature in Kelvin.
