The highest temperature at which well defined liquid and vapor states exist It may be defined as the highest temperature at which it is possible to liquefy a gas by pressure alone
The highest temperature at which a fluid can exist as a liquid or vapor Above this temperature the fluid is a gas and, regardless of the amount of pressure applied, cannot be liquefied
The highest temperature at which well defined liquid and vapor states exist It is sometimes defined as the highest temperature at which it is possible to liquify a gas by pressure alone
The temperature at the critical point A gas above the critical temperature will never condense into a liquid, no matter how much pressure is applied Most substances have a critical temperature that is about 1 5 to 1 7 times the standard boiling point, in kelvin
the maximum temperature to which a liquid can be heated and still remain a liquid Additional heating will cause the liquid to vaporize irrespective of pressure
