Helium
One example of a gas would be helium. Helium is used to fill up balloons and make them float.
Helium is lighter than air. so balloons filled with helium will float in air. warming will make them float or rise up faster.
Helium balloons float because helium gas is lighter than the surrounding air. This causes the balloon to be buoyant and rise up in the atmosphere.
Helium is lighter than air, hence balloons filled with helium will float and rise up.
The balloons that float usually contain helium in them, which is lighter than air. This enables the balloon to float.
Helium gas , because helium is the most inert element of all, and does NOT ignite, and allows balloons to float. If carbon dioxide was used, then the balloons would fall to the floor. Hydrogen is NOT used , because it is flammable and explosive, when mixed with air.
Magic...
Usually helium unless you're blowing it up yourself, then it's carbon dioxide.
Helium. Hydrogen works too but it tends to blow up. Helium is an inert gas that is very unreactive so it makes the best option.
Balloons blown up by mouth can fly briefly due to the air pressure inside causing them to float for a short period of time. However, they will eventually lose air and fall back down. helium-filled balloons are typically used to make them float for longer periods.
Helium gas is typically used to fill balloons to make them float or fly. Helium is lighter than air, so it causes the balloon to rise due to the difference in density between the helium gas inside the balloon and the surrounding air.
Yes it will, if it's inside the balloon and hot enough.It actually won't. CO2 is a heavier gas than Earth's atmosphere, so it will sink. Think about it- we breathe out carbon dioxide, and balloons we blow up the normal way don't float.
