Why Does a Metal Ball Expand When Heated

Heating the ball made the molecules of the metal vibrate faster, so they pushed each other farther apart. This made the metal ball expand (substance), so it would no longer fit through the ring. … This allows the molecules to move closer together, so the solids contract.

What happens when a metal ball is heated?

A metal ball is made up of atoms having minimum interatomic distance, so when we heat the metal its atoms actually vibrate about their mean position and thus colliding with neighboring atoms and making them to vibrate, due to this continuation process metals size increases or metal expands on heating.

Why does an object expand when heated?

When a solid is heated, its atoms vibrate faster about their fixed points. … Heat causes the molecules to move faster, (heat energy is converted to kinetic energy ) which means that the volume of a gas increases more than the volume of a solid or liquid.
