SIVR-106 1. A balloon is a type of object that uses gas to rise or float in the air. Using this idea, describe how a helium balloon can float through the air. The gas helium is lighter than air, and as a result, helium balloons float in the air. In other words, when a balloon is filled with helium, the helium's low density causes it to float upward through the air. ## The concept of density describes how compact an object is. Using this idea, explain how a helium balloon can float through the air. Helium has a lower density than air, causing it to rise and float in the air. When a balloon is filled with helium, it becomes lighter than the surrounding air, and as a result, the balloon floats upward. ## 1. A balloon is a type of object that uses gas to rise or float in the air. Using this idea, describe how a helium balloon can float through the air. ## Guiding Answer: a helium is lighter than air, and as a result, helium balloons float in the air. In other words, when a balloon is filled with helium, the helium's low density causes it to float upward through the air. ## A kilogram of water weighs 1 kilogram. Using this idea, explain why a helium balloon can float through the air. The helium balloon is lighter than the air of its surroundings, causing it to float and rise above the ground. This concept of low weight versus weight causes the balloon to float. ## Explain why a helium balloon can float through the air using the concept of density. The helium has a lower density than air, causing it to rise and float in the air. In other words, when a balloon is filled with helium, the helium's low density causes it to float upward through the air.
