Abstract
The critical temperature Tc, critical pressure Pc, and critical molar volume Vc are the values of the temperature, pressure, and molar volume at which the densities of the liquid and gaseous phases become identical. The critical density ρc = M/Vc, where M is the molar mass. At temperature above the critical temperature a gas cannot be liquified. With the appropriate conditions of temperature, pressure, and volume, the critical point may be identified by visual observation of the disappearance and reappearance of the meniscus between liquid and vapor.
