they can follow clouds or storms.
helium
Helium is the noble gas used in party balloons and weather balloons because it is lighter than air. Its low density makes it ideal for filling balloons as it provides buoyancy without adding much weight.
it is esay thay have air <_>
No, it is not. "Regular" air is used, and it is heated. Hot air is less dense than cooler air, and it will rise. If hot air is trapped in an envelope, it will give lift to the envelope and an attached payload.
No, hot air balloons are typically filled with hot air to become buoyant and rise. Helium is an alternative gas used in some balloons, like party balloons or weather balloons, due to its lighter weight than air.
The air. A craft that can be in the air is usually used (couldn't use a ship eh?) such as an aeroplane or helicopter. During the first world war airships and reconnaissance balloons were used. Weather balloons and satellites can be used nowadays.
Meteorological balloons are made from natural latex rubber, mostly in Japan.
Hot air balloons do not use helium; they are typically filled with hot air. Helium is non-flammable and more commonly used in other types of balloons like weather balloons or party balloons. The hot air inside a hot air balloon is what allows it to rise and float.
Hot air balloons are now mostly used for leisure
Weather balloons collect data about the weather by carrying instruments called radiosondes high up into the atmosphere. These instruments measure temperature, humidity, and air pressure as the balloon ascends. The data is transmitted back to the ground, where it is used to create weather forecasts and study atmospheric conditions.
Balloons can demonstrate principles of physics, such as the relationship between air pressure and volume. The properties of balloons can also be used in experiments to study gases and buoyancy. Additionally, balloons are used in scientific research, weather monitoring, and to collect atmospheric data.
A weather balloon is something that people who study weather send up into the air to learn more about weather and find weather patterns.
