Question of The Day09-11-2022

Conditions under which a gas can be liquefied are- 

Answer

Correct Answer : b ) Low Temperature and High Pressure

Explanation :

Gases have very high kinetic energy which results in random motion and increased intermolecular distance. To bring the substance from the gaseous phase to the liquid phase we must bring the particles closer by reducing the kinetic energy. A decrease in temperature reduces the kinetic energy of the particles thereby bringing them close, now with the application of high pressure the gaseous molecules can be pushed together to form a liquid.

Hence, option (b) is correct.
