Because it can flow.
Helium-4 is a strange super fluid and flow easily.
Helium can exist in both liquid and gas states. At extremely low temperatures, around -269°C, helium can turn into a liquid. This makes helium unique among the elements, as it can exhibit both fluid behaviors as a liquid and gas.
Helium gas was used as a thermometric fluid"
Because helium is lighter than air. An object in a fluid is buoyed up by a force equal to the weight of the displaced fluid. That's the reason that soap, logs, people, and boats float in water, and bags of hydrogen, hot air, or helium float in ordinary air.
Gravity works on Helium the same as it works on everything else. But the higher air pressure at sea level (caused by gravity compressing air particles at the surface) works against Helium to squeeze it upwards. This effect is called buoyancy, where a fluid of lesser density (Helium) is pushed away by a fluid of higher density (normal air). It's the same effect you see when a ball full of air is pushed into water.
It would help to know what volume was to be converted!
Balloons are filled with gas (such as helium), or a mixture of gasses (such as air) or hot gasses (such as hot air).Helium.
Any object surrounded by a fluid is buoyed up by a force equal to the weight of the fluid it displaces. There's an upward force on a cork in water that's equal to the weight of the water it displaces. There's an upward force on a helium balloon that's equal to the weight of the air it displaces. It so happens that a balloon full of helium weighs less than the air it displaces, so the upward force on it is greater than its weight.
A steel tank filled with helium gas does not rise in air because the weight of the tank and the helium gas inside is still greater than the buoyant force acting on it. The buoyant force is the force that causes objects to float in a fluid, like air. Since the tank is heavy and the helium gas is not strong enough to lift it, the tank remains on the ground.
No; the process of separating water into oxygen and helium gases is called electrolysis, since it uses electricity (and a catalyst, such as platinum) to do so.Distillation is the process of concentrating a fluid (such as alcohol) by separating it from another fluid (such as water) by taking advantage of the fact that the fluids will boil at different temperatures. It is a heat-based process, rather than an electrical one.
Gas would not be considered a fluid. A good example of fluid is water. Anything that is a liquid is a fluid. The examples of gases are; carbon dioxide, hydrogen, nitrogen, oxygen, methane, helium, argon, sodium, chlorine and sulphur.
Helium floats because it is lighter than the surrounding air. The density of helium is lower than that of the nitrogen and oxygen that make up most of the atmosphere, which allows helium-filled balloons to rise. This buoyancy effect occurs due to the principles of displacement and Archimedes' principle, where an object will float if it displaces a weight of fluid greater than its own weight.
