An ideal gas can never 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

D. forces operating between its molecules are negligible
Correct Answer – D
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.
