An ideal gas cannot be liquefied because

Question

An ideal gas cannot be liquefied because (A) its critical temperature is always above 0° C (B) its molecules are relatively smaller in size (C) it solidifies before becoming a liquid (D) forces operating between its molecules are negligible

Tardigrade Admin · Accepted Answer

Gases can be liquefied by lowering the temperature and increasing the pressure. An ideal gas have no intermolecular force of attraction, so it cannot be liquefied by applying high pressure and decreasing temperature.

Q. An ideal gas cannot be liquefied because

its critical temperature is always above $0^{\circ} C$

its molecules are relatively smaller in size

it solidifies before becoming a liquid

forces operating between its molecules are negligible
