Solution

The correct option is B False
Liquid nitrogen is nitrogen in a liquid state at an extremely low temperature. Hence, At low temperature, nitrogen can be liquefied on compression.
This liquification is possible due to compression below critical temperature. Hence, the statement 'At any temperature, nitrogen cannot be liquefied on compression' is false.

State True or False.

At any temperature, nitrogen can be liquefied on compression.

The critical temperature of ammonia and hydrogen are 405.5K and 33.2K respectively. Ammonia can be liquefied at room temperature just by compression of the gas at high pressure. Liquifaction of hydrogen , on the other hand, requires cooling as well as compression. (True/False)

Consider the following statements.

I. Gaseous substances whose critical temperatures are above room temperatures can be liquefied by applying sufficient pressure to the gas.

II. Gaseous substances whose critical temperatures are below room temperature can be liquefied by the application of pressure and lowering of temperature below $T_{c}$ .

Select the correct alternate.

Q. The temperature below which a gas must be cooled before it can be liquefied by compression is called as .

Q. Assertion :A gas can be easily liquefied at any temperature below its critical temperature. Reason: Liquification of a gas takes place when the average kinetic energy of the molecules is low.
