Aburning piece of coal glows red on a lab table. a student wants to prevent the coal from transferring heat to him. he sets up a metal shield between himself and the coal to prevent convection. why will this not completely stop all of the heat transfer? the metal shield will heat up, and then heat the air on the student's side of the shield. the metal shield will cause more radiation to reach the student. the metal shield will not prevent heat transfer by conduction. the metal shield cannot block the flow of fluids.

Option (A) is the correct answer.

Explanation:

It is known that metals are good conductors of heat and electricity. As a result, they are able to pass on the heat in air or another substance.

For example, when a metal shield is placed between student and the coal to prevent conduction then transfer of heat will not stop completely.

This is because metal shield will transfer the heat into the air due to which air becomes hot and the student will feel the heat.

Thus, we can conclude that metal shield will not completely stop all of the heat transfer because the metal shield will heat up, and then heat the air on the student's side of the shield.

I DON'T NO
