What are the differences between a hydrogen balloon and a helium balloon in terms of safety, buoyancy, and availability?
Hydrogen balloons are more flammable and pose a higher safety risk compared to helium balloons, which are non-flammable. Helium balloons have better buoyancy and can lift heavier loads than hydrogen balloons. Helium is more readily available and safer to use compared to hydrogen, which is more difficult to obtain and handle safely.

What gases lift a balloon into the air?
Anything less dense than air (hydrogen, helium, hot air).
Why does a balloon filled with not air rises?
A balloon filled with a gas less dense than the surrounding air, such as helium or hydrogen, rises because of the principle of buoyancy. The lighter gas inside the balloon creates an upward force that is greater than the weight of the balloon itself, causing it to float upwards.
How do you measure the buoyancy of a balloon?
The buoyancy of a balloon can be measured by comparing the weight of the balloon and its contents to the weight of the air that it displaces. By measuring the difference in weight, you can determine the buoyant force acting on the balloon. This can be done using a scale and by conducting experiments in controlled environments.
I am lighter than air but a hundred people can't lift me What am I?
The answer is a balloon. Balloons are lighter than air due to the helium or hydrogen gas they are filled with, but even with a hundred people, they cannot be lifted due to their buoyancy and the mass of air displaced by the balloon.
What is the formula for Buoyancy in balloons?
The buoyant force acting on a balloon is equal to the weight of the air displaced by the balloon. The formula for buoyancy in balloons is: Buoyant force = Weight of air displaced = Volume of balloon * density of air * g, where g is the acceleration due to gravity.
What did James Glaisher make his balloon with?
James Glaisher made his balloon with silk fabric coated in rubber to make it airtight. The balloon was filled with hydrogen gas for buoyancy.
What gases lift a balloon into the air?
Anything less dense than air (hydrogen, helium, hot air).
How are hydrogen tanks used in balloons for lifting and floating purposes?
Hydrogen tanks are used in balloons to provide the gas needed for lifting and floating. The hydrogen gas is lighter than air, so when it is pumped into the balloon, it creates buoyancy that allows the balloon to rise and float in the sky. The tanks are securely attached to the balloon and release the hydrogen gas as needed to maintain the desired altitude.
What gas can make a balloon float Is it hydrogen or Nitrogen or Argon or Chlorine?
Hydrogen can make a balloon float. Nitrogen, argon, and chlorine will not. However, hydrogen is combustible and in a balloon that cam near an ignition source, could produce a fire or explosion. The preferred gas for balloons, if cost is not an issue, is helium, which does not burn and is still very light.
When you replace helium in a balloon with less dense hydrogen does the buoyant force on the balloon change if the balloon remains the same size?
Yes, the buoyant force on the balloon will increase when less dense hydrogen is used instead of helium. This is because hydrogen is even less dense than helium, so the overall density of the balloon-hydrogen system decreases, leading to a greater displacement of air and therefore a stronger upward buoyant force.
Why does a balloon filled with not air rises?
A balloon filled with a gas less dense than the surrounding air, such as helium or hydrogen, rises because of the principle of buoyancy. The lighter gas inside the balloon creates an upward force that is greater than the weight of the balloon itself, causing it to float upwards.

Why and how does a hot air balloon fly?
Air expands when it is heated. This makes it less dense than colder air. Hence, it has buoyancy, and tends to rise. If it is trapped in a balloon, it can take the balloon up with it, along with things attached to the balloon, as long as the buoyancy of the balloon exceeds the attached weight.
What causes a hot air balloon stay afloat?
the buoyancy
What makes a balloon rise on air?
A balloon rises on the principle of buoyancy. This occurs when the net pressure on the bottom of the balloon exceeds the net pressure on top of the balloon.
I am lighter than air but a hundred people can't lift me What am I?
The answer is a balloon. Balloons are lighter than air due to the helium or hydrogen gas they are filled with, but even with a hundred people, they cannot be lifted due to their buoyancy and the mass of air displaced by the balloon.
Is a blimp a type of hot air balloon?
No, a blimp is not a type of hot air balloon. While both are inflated with gas to become buoyant, hot air balloons rely on heated air to rise, while blimps are powered by engines and filled with helium or hydrogen gas for lift.
