Liquid State

Vapor Pressure

1. Vapor pressure is the pressure exerted by the vapor of a liquid in equilibrium with its liquid phase at a given temperature.
2. It depends on the temperature and the nature of the liquid.
3. As the temperature increases, the vapor pressure also increases due to higher kinetic energy of the molecules.
4. A liquid with a higher vapor pressure at a given temperature is considered more volatile.
5. The temperature at which the vapor pressure equals atmospheric pre
