Question

When a candle is lit , what happens to the rod just above it ? ​

Answer 1

Answer:

If one end of a metal rod is heated, the other end also gets heated up. This is due to conduction. When one end of a metal rod is heated, the kinetic energy of the molecules at that end increases. ... Thus heat transfer takes place by conduction.

The metal particles start to vibrate faster and collide with their neighbouring particles. These collisions spread the thermal energy up through the teaspoon. This makes the handle of the teaspoon feel hot. Conduction is the transfer of thermal energy between objects that are touching.

         

Answer 2

Energy is transferred to the metal of the rod just above it. The thermal energy of this part of the rod increases and the rod becomes hot. Which pin or paperclip dropped off the metal rod first.
