MCQ
An ideal gas obeying kinetic gas equation :
  • ✓
    can be liquefied if its temperature is more than critical temperature
  • B
    can be liquefied at any value of any value $T$ and $P$
  • C
    can not be liquefied under any value of $T$ and $P$
  • D
    can not be liquefied under any value of $T$ and $P$
✓

Answer

Correct option: A.
can be liquefied if its temperature is more than critical temperature
An ideal gas is meant to have no intermolecular force of attraction
That's why a real gas has to reach, lowest pressure and highest temperature enough to overcome the intermolecular force of attraction and behave like an ideal gas.
So ideal gas can't be liquefied at any $T$ and $P.$
