A hot-air balloon pilot controls the balloon by

adding or releasing hot air as the balloon flies

high above Earth.

Which of these describes why hot air is used to

make the balloon rise?

• The heated particles stay still, which creates

  energy that helps the balloon to float.

• The heated particles are dense, or tightly

  packed together, to make the balloon rise.

  energy and causes the balloon to rise in the air.

• The heated particles move quickly, bouncing off

  each other and the walls of the balloon to create

  energy.
