) the three correct sentences. The hot air balloon has the most kinetic energy when moving the fastest. The hot air balloon has the most kinetic energy after it has landed on the ground. The chemical energy in the propane fuel is changed into heat energy. The hot air balloon has no light or sound energy when it is travelling through the air. The hot air balloon has the most potential energy when it is the highest in the sky. [2]
