At what pressure does $SO_2$ gas liquefy at room temperature?

Critical temperature for carbon dioxide and methane are $31.1^{\circ} C$ and $-81.9^{\circ} C$ respectively. Which of these has stronger intermolecular forces and why?

What is the temperature below which a gas cannot exist as a gas (i.e.,it liquefies) called?

Which set of conditions represents the easiest way to liquefy a gas?

The temperature and pressure at which ice,liquid water,and water vapour can exist together are:

However great the pressure,a gas cannot be liquefied above its
