The ball can pass freely through the ring when both are at the same temperature. However, when the ball is heated, it undergoes thermal expansion and no longer fits through the ring. Once it cools down, it contracts and is again able to pass through.\u003c\/p\u003e\n\u003cp\u003eAt a microscopic level, when the brass ball is heated, the kinetic energy of its molecules increases.
