Question

What are good conductors of heat? Give two examples.

Answer 1

1. Materials which conduct heat readily are called good conductors of heat .
2. Example: iron, copper and aluminium.
3. Generally, all metals are good conductors of heat.
4. Conduction of heat in metals is due to valency electrons which are free to move around the inner surface.
5. When heated, these free electrons collide with each other and the majority of the kinetic energy is converted into heat energy making metals good conductors.
