NEET levelSingle correct optionDifficulty 1 of 3rg034

The critical temperature of a gas is

  1. Athe temperature at which the gas has maximum density
  2. Bthe highest temperature at which the gas can be liquefied by applying pressure
  3. Cthe temperature at which
  4. Dthe lowest temperature at which the gas remains a gas

Answer: B

Above the critical temperature no amount of pressure can liquefy the gas because the kinetic energy exceeds the attractive interactions. is therefore the highest temperature at which liquefaction by compression is possible.
