If the lid of a jar containing helium gas is removed, the helium gas will quickly diffuse out of the jar and into the surrounding environment because helium gas is lighter than air. Helium is also non-toxic and non-flammable, so it will not pose any immediate danger.
If you had retracting magnets on a pencil and you removed the pencil, the magnets would retract back into their original position due to the force of attraction being removed. The retracting mechanism would work by using a spring or other mechanism to pull the magnets back into place once the pencil is removed.
If energy is removed from liquid water, it would cool down and eventually freeze into solid ice at its freezing point (0 degrees Celsius or 32 degrees Fahrenheit).
If the balloon was removed from the flask, the mass of the flask and its contents would remain the same because the air inside the balloon is still part of the system. Removing the balloon does not change the total mass of the system.
No, it wouldn't work the matteral is too heavy
Helium gas is commonly used to make balloons float. Helium is lighter than air, so filling a balloon with helium makes it buoyant and able to float.
The helium, being lighter than air, would simply rise out of the jar.
That would happen after it loses a certain amount of helium.
The bottle will just feel like a bottle full of air. In order for it to float like a balloon filled with helium, it would have to weigh less than air or you would need to fill the bottle to well over its capacity. 1 cubic meter of helium is required to lift 1kg.
The Helium gas will expand and rise into the suurounding the air as it is less dense and lighter air. Depending on the amount of helium and the size of the room the Helium could displace the breathable mix in the space and become a danger to health.
the lighted splint would stop burning as Helium does not burn.
A single proton was most likely removed from the helium atom to result in an atom of hydrogen. Helium typically has two protons, so removing one proton would leave one, transforming it into hydrogen, which has one proton.
If one electron has been removed from Helium's electron shell then it is a He+ ion. If both of its electrons have been removed it becomes a He2+ ion. Either way they are both positive ions.
it would be cray.
we would die
Helium is chemically inert and does not combine with any other element (including thallium).
The reaction in the sun which gives us energy involves helium. If helium didn't exist we would receive no energy and life wouldn't exist on the earth.
If both lungs were removed, the person would die.
