What happens when atoms are heated?

Answer 1

When an atom is heated the electrons in orbit around the nucleus move into a higher-energy orbit, moving further away from the nucleus. When the electron moves back, into a low-energy orbit, it sets off a particle of light, known as a photon.

Answer 2

Answer 2 Heat will add energy to the substance, and this will result in the molecules having greater velocity.

Some, if in a liquid, will capture enough energy to be able to leave the surface of the liquid. With enough heat, the boiling point of the liquid will be reached, and the liquid will change phase completely into a vapour / gas.

If the substance were a solid, the increase in inter-molecular velocity will become great enough to melt the solid - to break the inter-molecular bonds.

Gwen is cool!

Answer 3

Heat is the motion of atoms and molecules. If something is heated, its atoms or molecules dance around faster. If something loses heat, the atoms and molecules dance around less vigorously. At absolute zero temperature, atoms or molecules stop dancing around altogether.

Answer 4

They vibrate more. That's actually the definition of heat.

Answer 5

The atoms heat up and break into smaller particles. It then will do the same for molecules. Heating matter can make particles in it to move around severely. It takes less time.
