Webb25 apr. 2024 · If rubber behaved like other substances when warm, it would expand. However, because of the arrangement of the rubber molecules, the band becomes smaller. Heating them "unwinds" the tangled balls, making the molecules less bunched and more strand-like. In this form the molecules take up less space and the rubber band shrinks. … Webb9 feb. 2024 · When metal ball is heated, it expands. This can be proved by following experiment: Take a metallic ring and ball. Try to pass the metal ball through the ring. The ball is able to pass through the ring.
