In a kinetic model explain why a metal rod expands when heated​

Heat expansion

Explanation:

Heat expansion is when air bubbles get trapped in a chemical while heating,the bubble gets bigger and the host expands,therefore causing heat expansion.

When a solid is heated, its atoms vibrate faster about their fixed points. The relative increase in the size of solids when heated is therefore small.
