What property of helim makes it good for filling balloons?
Helium is a lightweight, inert gas which makes it safer than other gases. It is also non-toxic, non-flammable, and does not react with other chemicals, making it ideal for filling balloons. Additionally, helium provides buoyancy, allowing balloons to float.
What gases makes balloons float?
Helium is the gas most commonly used to fill balloons for them to float. It is lighter than air, so it provides lift when contained within a balloon. Hydrogen gas can also be used, but it is flammable, which makes it less commonly used than helium.
What gas does make a balloon float?
Helium gas is commonly used to make balloons float. Helium is lighter than air, so filling a balloon with helium makes it buoyant and able to float.
What makes balloons float when they are full of air but not float when they are deflated?
Balloons float when they are full of air because the helium or air inside is less dense than the surrounding air, creating buoyancy. When they are deflated, the balloon is denser than the surrounding air, causing it to sink rather than float. This is due to the principle of buoyancy and the difference in density between the balloon and the air.
Why do baloons float in air?
Balloons float in air because they are filled with a gas that is lighter than the surrounding air, usually helium or hydrogen. This creates a buoyant force that pushes the balloon upward, causing it to float.
