Question

Explain with the help of an activity that metals are good conductors of heat

Answer 1

♦ As we know Metals are good conductors of both heat and electricity.

♦ Here is a simple experiment to test whether metals are good conductors or not.

♦ First Let's take a bulb and metal wire.

♦ If we connect bulb to the a metal wire and connect wire's end through the battery then,then bulb will glow. which shows that metal is good conductor of heat and electricity.

♦ Now take a wooden scale instead of  metal wire. And if we connect bulb through a wooden scale,then bulb will not glow. So,this shows it is bad conductor of heat and electricity.

Answer 2

Heyy there,

Here's your answer...

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.
