Answer 2

Answer:

Metals are a good conductor of heat.

This can be experimentally proved by the following activity:

Take a glass rod, a silver spoon and a plastic scale. Dip all three in a beaker containing boiling water. Leave the setup for 2-3 mins and touch each of the three, the glass rod, the silver spoon and the plastic scale. You would feel that only the silver spoon is hot.

Thus, it is proved that metals(in this case silver) are good conductors of heat.
