39.Critical temperature for carbon dioxide (CO2) and methane (CH4) are 31·1°C and –81 ·9°C respectively. Which of these has stronger intermolecular forces and why?
The rapid motion and collisions of molecules with the walls of the container causes pressure. Pressure is proportional to the number of molecular collisions and the force of the collisions in a particular area. The more collisions of gas molecules with the walls, the higher the pressure.
