Yes. Helium is normally a gas at the temperature and pressure we are likely to find in the ordinary room. Like other gases, helium is easily compressed. A gas compressing machine compresses helium gas and stores it in metal cylinders. You can see one for yourself anywhere helium filled balloons are sold. Look for a tall, thin metal container with a valve and a pressure gauge on the top. The cylinders I have seen were brown, about as big around as a Basketball, and about as tall as a fifth grader.
No, helium does not readily undergo any chemical reactions.
yes helium does have a lot of pressure.
Helium does not burn because it is an inert gas, meaning it does not undergo chemical reactions like combustion.
The pressure that there would be if all the non-helium atoms and molecules were taken away.
no. it is not known to undergo any checmical reactions
The pressure that there would be if all the non-helium atoms and molecules were taken away.
The relationship between helium pressure and its effects on gas-filled balloons is that as the pressure of helium inside the balloon increases, the balloon expands and rises. This is because the higher pressure of helium pushes against the walls of the balloon, causing it to inflate and float.
Gas under high pressure
No, helium is an inert gas and does not readily undergo chemical reactions. It is not a good reducing agent as it does not have the ability to donate electrons to other substances.
At 20°C and one atmosphere of pressure, helium is not a solid. Helium exists as a gas at this temperature and pressure.
helium is chemically inert and doesn't undergo combustion reaction
A star is a giant ball of hot gases that undergo nuclear fusion in its core. The intense pressure and temperature at the core of a star cause hydrogen atoms to fuse together to form helium, releasing a tremendous amount of energy in the process.
