As CJ and Ella cook breakfast for their family, they discuss what they have been learning in science class about the transfer of thermal energy.
CJ notices that the burner on the stove gets extremely hot, but thinks that the food never gets quite as hot as the burner. He says this happens because some of the thermal energy is lost as it transfers from the stove to the food.
Ella explains that he is partially right and partially wrong. She says that his observation is correct, but his conclusion is incorrect.
