Key:
KE = kinetic energy
PE = potential energy
Note- the areas between have potential and kinetic energy because they are changing from one energy to the other.

Filling a hot air balloon
Heat TransferHeat is transferred from warm to cool places. The heat energy in this cup of hot coffee moves from the hot coffee to the cup, to the counter it’s sitting on and also to the cool air surrounding it. This transfer of heat causes the coffee to cool down.
Quiz:
What is the correct order of heat transfer for this situation?
Fire to air to pizza to grill
Pizza to grill to air to fire
Air to fire to grill to pizza
Fire to grill to pizza to air
