critical volume
critical volume n (General Physics) the volume occupied by one mole or unit mass of a substance in its critical state Critical Volume
critical volume[′krid·ə·kəl ′väl·yəm] (physics) The volume occupied by one mole of a substance at the liquid-vapor critical point, that is, at the critical temperature and pressure. Critical Volume the specific volume of a substance (or mixture of substances) in its critical state. The specific volumes of the liquid and gaseous phases in the critical state become equal. This specific critical volume corresponds to a density approximately three times lower than the density of the substance in the solid state. (For values of the critical volume Vc of a number of substances, see .) |
