Unformatted text preview: helped the sound of the tuning fork become louder. Does sound travel through carbon dioxide faster or slower than air? Yes, sound travels faster through carbon dioxide than air. Does it help to know that carbon dioxide molecules are 1.5 times as massive as air molecules? Yes, because a denser gas will make the sound travel faster. Could the balloon act like a lens focusing the sound toward your ear? Yes, because the balloon creates more surface area for the sound to travel on. Generalizations: A balloon next to your ear can make a tuning fork sound louder. Without the balloon next to your ear the tuning fork will not be as loud. The surface area is much larger when the balloon is there and makes the sound louder. Also sound travels through a solid faster than through a gas. To improve this experiment you could fill up the balloons with different gases and describe how loud the tuning fork is....
