Heated metal rod
WebAs atoms vibrate faster, the space between atoms increases. . The motion and spacing of the particles determine the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space. So, When a metal rod is heated it expands because of the distance among its atom increase.
