9.2.7.1 Basic Definitions Critical temperature (T c)The maximum temperature at which a gas can be converted into a liquid by an increase inpressure. Critical pressure (p c)The minimum pressure which would suffice to liquefy a substance at its criticaltemperature. Above the critical pressure, increasing the temperature will not cause a fluidto vaporize to give a two-phase system.
The vapor pressure that a single component in a mixture contributes to the total pressure in the system is called partial pressure. For example, air at sea level, and saturated with water vapor at 20 Â°C, has partial pressures of about 2.3 kPa of water, 78 kPa of nitrogen, 21 kPa of oxygen and 0.9 kPa of argon.apor pressure or equilibrium vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a closed system. The equilibrium vapor pressure is an indication of a liquid's evaporation rate.
