A sealed, rigid steel cylinder contains a sample of helium gas. The cylinder is moved from a warm laboratory into a cryogenic cooling chamber, causing the temperature of the gas to decrease significantly.
The volume of the cylinder remains constant.
By considering the motion, speed, and collisions of the helium atoms, explain how this temperature decrease affects:
