Vapor pressure is the pressure exerted by a vapor in equilibrium with its liquid or solid phase at a given temperature. For water, the vapor pressure increases with temperature. At 20°C (68°F), the vapor pressure of water is approximately 17.3 mmHg (or 2.34 kPa). At 100°C (212°F), the vapor pressure reaches 760 mmHg (or 101.
