Vapor Pressure

Subject: Chemistry

Book: General Chemistry

Vapor pressure is the pressure exerted by a vapor in equilibrium with its liquid or solid phase at a given temperature. It increases with temperature, as more molecules have enough kinetic energy to escape into the vapor phase. Volatile substances have higher vapor pressures, leading to faster evaporation. Understanding vapor pressure is fundamental for distillation, boiling point determination, and material selection in various processes.
