What evidence from the experiment shows that conduction occurred? In your answer, be sure to include the materials involved in the transfer of heat through conduction.

Answer:

Evidence that conduction occurred is seen when the chocolate pieces melt one after the other starting from the end closest to the heat source. Heat energy moved through the aluminum foil bridge, and since the chocolate pieces were in direct contact with the foil, heat was transferred to them through conduction.
