Question

you and your lab group have been asked to design an investigation to determine the effects of heat transfer between two different objects. which of the following investigation designs explains the heat transfer when atoms directly touch?

oa boiling water, in a pan, in front of a lit bunsen burner.

ob hands touching the handle of pan sitting on a lit bunsen burner.

oc boiling water, in a pan, sitting on a lit bunsen burner.

od hands warming in front of a lit bunsen burner.

Explanation:

Heat transfer by direct - atom contact is conduction. In option B, hands touching the pan handle is conduction as atoms in the hot pan handle transfer heat to atoms in the hands. Option A is mainly about convection in the water and radiation from the Bunsen burner. Option C is convection in water and heat transfer from burner to pan. Option D is radiation from the Bunsen burner to hands.

Answer:

B. Hands touching the handle of pan sitting on a lit Bunsen burner.
