False. Most substances contract or shrink when they are cooled down because cooling reduces the kinetic energy of the particles in the substance, causing them to move closer together.
Most substances change their physical state and transition from solid, to liquid, to gas when heated or cooled. This phase transition occurs due to changes in the arrangement and movement of the particles within the substance.
