Question

Gases can be liquified at low temperature and low pressure.

✓

Answer

False.
Explanation:
Gas cannot be liquefied by compression unless its temperature is below the critical value when it will be considered a vapour. Similarly, cooling will liquefy a gas only if the pressure is above the critical. Conversely, a liquid will boil at low pressure even with temperature held constant.
