Answer to Question #212506 in Atomic and Nuclear Physics for hani

Question

in which substance are free electrons involved in transfer of energy

Answer 1

Matals are free electron involved in tranfer of energy

For example

Gold , aluminium , copper , silver etc are conducter .

Metals contain free electrons that are mobile.

When heated, these free electrons gains KE and will diffuse to the cooler end at high speeds.

In the process, they will collide with atoms at the cooler end and transfer kinetic energy to them.
