helium gas
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.
Helium gas is commonly used to make balloons float because it is lighter than air and creates lift. The helium gas in the balloon is less dense than the surrounding air, causing the balloon to rise.
Helium gas is commonly used in balloons sold by vendors to make them float.
Yes, a helium-filled balloon will float in the air because helium is less dense than the surrounding air. When filled with helium, the balloon experiences a buoyant force that causes it to rise and float.
Helium gas is lighter than air and hence balloons filled with helium will float in air.
Usually helium, the lightest noble gas. You can make a balloon or bag float with hydrogen gas, but it is flammable. Pure nitrogen is only slightly lighter than air, so it would not lift very effectively.
Yes.
Helium gas is most commonly used to fill balloons to make them float. Helium is lighter than air, which causes the balloon to rise and float.
When helium is added to a balloon, it decreases the overall density of the balloon compared to the surrounding air. This causes the balloon to float because the buoyant force exerted by the helium is greater than the force of gravity acting on the balloon. This buoyant force allows the balloon to rise in the air.
Yes.... See Hindenburg.
Carbon dioxide, the air we have in us that we breath out. Carbon dioxide doesn't make the balloon float in the air, while Helium does.
Helium is the gas commonly used to fill balloons to make them float. If a balloon is filled with a gas heavier than air, such as carbon dioxide or nitrogen, it will cause the balloon to drop instead of float.
