Types of Energy

Using the models, which station was most of the energy from the light sources transferred to the sand?

• Station A, because the sand is receiving the most direct heat transfer by radiation.

• Station A, because the sand is receiving the most direct heat transfer by conduction.

• Station D, because the sand is receiving the most direct heat transfer by radiation.

• Station D, because the sand is receiving the most direct heat transfer by conduction
