Definition of critical temperature in English: critical temperaturenoun Chemistry The temperature of a gas in its critical state, above which it cannot be liquefied by pressure alone. Example sentencesExamples - The critical temperature of water is 705.3°F.
- At some critical temperatures, nuclear fusion will begin to occur.
- This question cannot be addressed in the laboratory setting because it is impossible to prevent phase separation at temperatures below the critical temperature of mixtures lying between the coexistence curves.
- Replacing the water with alcohol and evaporating the alcohol above its critical temperature results in a silica aerogel, in which the original arrangement of silica particles is retained.
- Some authors use the term ‘fluids' for common gases and liquids; others restrict the noun ‘fluid’ to volatile substances at temperatures above their critical temperatures.
