(physics) Of a temperature that is equal to the temperature of the critical point of a substance, i.e. the temperature above which the substance cannot be liquefied. Essential That which is essential; first or constituent principle; as, the essentials of religion. Critical A critical value, ...
In principle, the critical point of a substance that decomposes at a temperature below its critical temperature cannot be measured experimentally. The measurement of the critical properties of a thermally stable substance requires fine temperature control to obtain data of high precision. Methods to ...
Critical point, in physics, the set of conditions under which a liquid and its vapour become identical (see phase diagram). For each substance, the conditions defining the critical point are the critical temperature, the critical pressure, and the critic
(General Physics) the state of a substance in which two of its phases have the same temperature, pressure, and volume. Also called: critical point Collins English Dictionary – Complete and Unabridged, 12th Edition 2014 © HarperCollins Publishers 1991, 1994, 1998, 2000, 2003, 2006, 2007,...

THE critical pressure of a substance is commonly defined as ``the least pressure that will suffice to reduce that substance from the gaseous to the liquid state when at its critical temperature.'' But this definition contemplates the matter solely from the stand point of what occurs at the ...
Can there be multiple critical points on a phase diagram? There is only one critical point on a phase diagram. It can be found at the end of the equilibrium line between liquid and gas. This is the point that once passed, the substance becomes a supercritical fluid. What is tr...
The meaning of CRITICAL VOLUME is the specific volume of a substance in its critical state : the reciprocal of the critical density.
