As a metal such as lead is heated past its melting point, what happens to the average kinetic energy of the atoms

The kinetic energy increases

Explanation:

As a metal such as lead is heated past its melting point, the average kinetic energy of the atoms increases.

When temperature is increased the kinetic energy of the atoms increase which also increases the random movement of the atoms.

When such happens the distance between the atoms is usually decreased which leads to the elastic collision that occurs.

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."
