Audrey pours hot chocolate into a cup. How is heat energy transferred?

• 
  Heat from the hot chocolate moves to the cup.

• 
  Cold from the cup moves to the hot chocolate.

• Heat energy does not move because the heat is in a liquid.

• Heat from the hot chocolate moves into the cup, and cold from the cup moves into the hot chocolate.
