Does a hot air balloon need CO2 to lift?
No, a hot air balloon does not need CO2 to lift. Hot air balloons work on the principle that hot air is less dense than cooler air, causing it to rise. When the air inside the balloon is heated, it becomes lighter than the surrounding air, allowing the balloon to lift off the ground.
What is something interesting about hot air balloons?
Hot air balloons were the first successful human-carrying flight technology, dating back to the 18th century. They operate on the principle that hot air is lighter than cool air, allowing them to lift off the ground. Hot air balloons offer a serene flying experience and are a popular choice for sightseeing and recreational air travel.
Why was hydrogen gas used in air balloons?
Hydrogen gas was used in air balloons because it is much less dense than air and therefore rises, taking the balloon with it. it is unfortunately also very explosive so not used often anymore.
How many balloons does it take to lift you up?
The number of balloons needed to lift a person depends on the weight of the individual and the lifting capacity of the balloons. A standard party balloon can lift about 14 grams (0.5 ounces) when filled with helium. For example, if a person weighs 70 kg (about 154 pounds), it would take around 5,000 balloons to lift them off the ground. However, this is a rough estimate and can vary based on balloon size and environmental factors.
What is the gas used in hot air balloon?
Air - a mixture of nitrogen, oxygen, carbon dioxide and other gases. When heated, air becomes less dense and so it will float in cooler (= more dense) air, giving the balloon its lift.Airships and blimps are different to hot air balloons in that they gain lift from an envelope (the balloon) filled with a gas that is lighter than air. In the past, this was hydrogen but use of this gas was stopped due to its extremely flammable nature and helium is now used instead.Used gasses in balloons: helium, hot air, hydrogen.
Can Balloons Really Lift A Person Off The Ground?
No, balloons cannot lift a person off the ground. The amount of lift produced by balloons is not enough to support the weight of a person. Additionally, the laws of physics would make it impractical for balloons to overcome the force of gravity acting on a person.
What element is used in a hot air balloon?
Hot air balloons typically use propane gas as a fuel source to heat the air inside the balloon envelope, causing it to rise and lift the balloon off the ground.
Does a hot air balloon need CO2 to lift?
No, a hot air balloon does not need CO2 to lift. Hot air balloons work on the principle that hot air is less dense than cooler air, causing it to rise. When the air inside the balloon is heated, it becomes lighter than the surrounding air, allowing the balloon to lift off the ground.
Which gas is used in hot air balloons?
Hot air balloons are typically filled with hot air, rather than a gas, in order to make them buoyant and rise in the air. The air inside the balloon is heated by a burner attached to the basket, which causes the balloon to lift off the ground.

How many balloons can lift a child?
The number of balloons needed to lift a child would depend on the weight of the child and the size of the balloons. On average, it may take around 80-100 helium-filled balloons to lift a small child off the ground. It's important to consider safety measures and proper balloon handling if attempting such a stunt.
How can air make an object lift off the ground?
Air cannot do that alone. Airplane wings are shaped such that a forward motion will force them to lift.
Why was hydrogen gas used in air balloons?
Hydrogen gas was used in air balloons because it is much less dense than air and therefore rises, taking the balloon with it. it is unfortunately also very explosive so not used often anymore.
How does something heavier than air stay off the ground?
lift
Why do hot air balloons have sand bags?
Modern hot air balloons do not have sand bags because the air input is easily controlled for lift. Hot air balloons used to have sandbags to weigh them down until lift off and sand was gradually dumped to gain height in the air.
What is the gas used in hot air balloon?
Air - a mixture of nitrogen, oxygen, carbon dioxide and other gases. When heated, air becomes less dense and so it will float in cooler (= more dense) air, giving the balloon its lift.Airships and blimps are different to hot air balloons in that they gain lift from an envelope (the balloon) filled with a gas that is lighter than air. In the past, this was hydrogen but use of this gas was stopped due to its extremely flammable nature and helium is now used instead.Used gasses in balloons: helium, hot air, hydrogen.
How are hot air balloons work?
Hot air balloons work by heating the air inside the balloon with a burner, which causes the balloon to become buoyant and lift off the ground. The hot air inside the balloon is lighter than the cooler air outside, creating a pressure difference that allows the balloon to float. By controlling the temperature of the air inside the balloon, the pilot can ascend or descend to navigate the balloon.
