Expert Answer:
The Vapor pressure is the pressure exerted by a vapor in the thermodynamic equilibrium with its condensed phases at a given temperature in the closed system. The equilibrium vapor pressure is an indication of a liquid's evaporation rate. It relates to the tendency of particles to escape from the liquid. A substance with a high vapor pressure at normal temperatures is often referred to as volatile.
