A thick-walled metal cylinder is sealed and filled with carbon dioxide gas.
Describe the arrangement and motion of the gas molecules inside this cylinder.
The cylinder is cooled down so that the temperature of the gas decreases. The volume of the cylinder does not change.
State and explain the change in pressure of the gas as its temperature decreases. Use ideas about molecular motion in your answer.
