What did you include in your response? Check all that apply.

A
The melting of the pieces of chocolate one by one is evidence that conduction occurred.
B
As heat flowed through the foil bridge, heat transferred to the pieces of chocolate, causing them to melt.
C
The heat transfer occurred between the foil bridge and the chocolate pieces, which were in direct contact with one another.

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.
