Question

Kim designed an experiment to show how heat can be transferred from one place to another. The steps of the experiment are shown below.

Coat one end of an iron rod with wax.
Dip the other end of the iron rod into a jar of hot water.
Observe the wax melt due to heat.
What does Kim's experiment most likely demonstrate?
heat transfer by convection

heat transfer by conduction

energy transfer by radiation

energy transfer by condensation

Answer 1

heat transfer by conduction, since kim is trying to show that heat travels from one end of the rod to the other. This is nothing but conduction

Answer 2

yup its conduction, because the energy supplied by the hot water gets transferred till it reaches the wax, which melts.
