Three friends are trying to figure out what happens when we put a hot bowl of rice into the cold fridge.

We know that if we put a bowl of hot rice into a fridge the rice will become cooler. We are not sure how hot rice becomes cooler.

  • Aubrey thinks that energy transfers cold and hot both move.

  • Kendrick thinks that energy transfers from the cold fridge to the hot rice.

  • Jermaine refuses to argue because he believes they are both wrong. He believes energy transfers from the hot rice to the cold fridge.
