What happens to the pressure inside a sealed canister of gaseous oxygen when it is transferred from a cool environment to a warmer environment?
The pressure increases when it is moved from a cool environment to a warmer environment. This is because the molecules of oxygen have more kinetic energy in a warmer environment and therefore move faster. The molecules of oxygen collide more frequently with the walls of the canister. The oxygen exerts a greater force on the walls of the canister increasing the pressure.
