Question

the aim of experiment to observing heat conductivity by metals write the material required procedure and precautions​

Answer 1

Answer:

Copper

Copper is a good conductor of heat. This means that if you heat one end of a piece of copper, the other end will quickly reach the same temperature. Most metals are pretty good conductors; however, apart from silver, copper is the best.

Answer 2

Materials required:

   A metal rod, few nails, plastic handle, candle and matches.

Procedure:

• Light the candle, melt the wax an d attach the nails to the iron rod.
• Make sure the nails are attached firmly.
• Now, place one end of the metal and heat it, hold the plastic handle carefully.
• Heat the rod and wait for sometime, you can see the nails fall off one by one starting from near the edge being heated and then followed by the ones near the handle.
• This proves the thermal conductivity of metals.

Precautions:

• Make sure to handle the candle flame carefully.
• Handle the nails with care.
