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.
Pressure. Pressure is defined as force per unit area. It is usually more convenient to use pressure rather than force to describe the influences upon fluid behavior.ut when you deal with a gas pressure, it must be approached as an average pressure from molecular collisions with the walls. Pressure in a fluid can be seen to be a measure of energy per unit volume by means of the definition of work.
