- ‘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.’
- ‘At some critical temperatures, nuclear fusion will begin to occur.’
- ‘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.’
