Critical temperature is the temperature above which the density of the substance in the gas and liquid state becomes identical.; After reaching the critical temperature condensation of the gas becomes impossible.; The critical temperature is specific for given substance.For example, the critical temperature of hydrogen (H 2) is -240.17 °C.
CRITICAL TEMPERATURE meaning in the Cambridge English critical temperature This condition implies that at the critical temperature the magnitude of the initial order parameter does not exceed its value at the superconducting state at temperature absolute zero. From the Cambridge English Corpus
Sep 23, 2020 · The critical point is the temperature and pressure at which the distinction between liquid and gas can no longer be made.
Critical Pressure - Definition and Detailed Explanation The critical temperature of a substance can, therefore, be defined as the pressure that must be applied to a substance in order to liquify it at its critical temperature. The critical pressure of a substance is often denoted by the symbol P C .
Critical Temperature and Pressure - Thermodynamics Aug 20, 2010 · In order to introduce the critical temperature and the critical pressure of a working substance (WS), consider the pressure - volume plot diagramed in Figure 1, which highlights the change in volume with the application of pressure for a fixed mass of gas, found at different constant temperatures.The various curves thus obtained (also called isotherms) are represented in Figure 1 in
Critical point:The end point of the pressure-temperature curve that designates conditions under which a liquid and its vapor can coexist. At higher temperatures, the gas cannot be liquefied by pressure alone. At the critical point, defined by the critical temperature T c and the critical pressure p c, phase boundaries vanish.

First Swell (Bud Swell) Tip Separation
Critical temperature Definition of Critical temperature Critical temperature definition, the temperature of a pure element or compound at a critical point:Above the critical temperature, no liquid can form, no matter how
At the critical point there is no change of state when pressure is increased or if heat is added. The triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium.
SuperconductivityThe critical temperature for superconductors is the temperature at which the electrical resistivity of a metal drops to zero. The transition is so sudden and complete that it appears to be a transition to a different phase of matter; this superconducting phase is described by the BCS theory.Several materials exhibit superconducting phase transitions at low temperatures.
Superconductors - Critical Temperatures of Some Pure Aug 14, 2003 · Critical temperatures (Tc) of some pure metals or type 1 superconductors. Some other elements do exhibit superconductivity, however require pressure at sufficiently low temperatures to induce superconducting behaviour.
Critical temperature definition is - the temperature of a substance in its critical state :the highest temperature at which it is possible to separate substances into two fluid phases (vapor and liquid).
