A science teacher filled one balloon with helium gas and a second balloon with carbon dioxide. The helium-filled balloon rose to the ceiling, and the balloon filled with carbon dioxide fell to the floor. Which statement is an inference based on this demonstration?
Each balloon behaved differently. Helium gas has a lower density than air. Carbon dioxide causes a balloon to expand. Balloons can be filled with different gases.
