You Can do an Experiment to Demonstrate Conduction

Question 1

What do you do attach to the metal bar?

Answer 1

Attach beads at regular intervals to one half of a long metal bar using wax

Question 2

What do you do to the metal bar second?

Answer 2

Hold it in a clamp stand, and, using a Bunsen burner, heat the side of the bar with no beads attached from the very end

Question 3

What happens as time goes on?

Answer 3

Energy is transferred along the bar by conduction and the temp increases along rod

Question 4

What will happen to the wax holding the beads in place?

Answer 4

It will gradually melt

Question 5

What will happen to the beads as temp increases?

Answer 5

They’ll fall, starting with the head closest to the point of heating - illustrating conduction
