D). Above which a gas will never liquefied
Answer: D) above which a gas will never liquefied.
Explanation: It is a temperatures at which vapors of a gas can't be liquefied.
No matter that how much pressure is applied on it. Every gasses have a critical temperature.
Above which a gas will never liquefied
The critical temperature of a substance is the temperature at and above which vapor of the substance cannot be liquefied, no matter how much pressure is applied.
