Question

With the help of an example explain that metals are good conductor of electricity while non-metals are not

Answer 1

Explanation:

• Metals are good conductors of electricity. The conduction of electricity is due to the number of free electrons flowing in it.
• Conductors have free electrons in it. As a result of which they can easily conduct electricity.
• Non metals do not conduct electricity. It is due to the lack of free electrons in it.
• But graphite is a non-metal that conducts electricity and it is a good conductor of electricity.

Answer 2

Answer:

When we put an aluminium vessel on a flame, after some time we will see that the surface of the metal away from the flame has become hot. But if we hold the rubber handle, we will see that there is no temperature change in the handle. this is because the aluminium (a metal) is a good conductor, while the rubber (a non-metal) is a bad conductor.

Hope it helps.
