Multiple Choice

What happens to the air particles inside a hot air balloon when heated using a small propane burner?

• The air particles move faster and spread out, decreasing density.

• The air particles slow down and come closer together, increasing density.

• The number of air particles inside the balloon increases.

• The air particles stop moving, causing the balloon to rise.
