Hydrogen cannot be liquefied at room temperature because
A)it is a diatomic gas
B)its critical temperature is less than the room temperature
C)37,500 kg
D)it has low density
E)it has high specific heat

Question

Quizplus · Accepted Answer

Hydrogen cannot be liquefied at room temperature because its critical temperature is below room temperature. The critical temperature is the maximum temperature at which a gas can be liquefied by pressure alone, and for hydrogen, this temperature is much lower than the typical room temperature, making liquefaction under these conditions impossible without significant cooling.
