To liquefy hydrogen at room temperature (around 20°C or 68°F), it requires extremely high pressures, typically around 100 atmospheres (approximately 10 MPa or 1,000 kPa). However, under normal atmospheric pressure, hydrogen cannot be liquefied at room temperature; it needs to be cooled to cryogenic temperatures (below -252.9°C or -423.2°F) to achieve liquefaction.

How much volume would a kilogram of gaseous hydrogen take up?
At standard temperature and pressure conditions, 1 kilogram of gaseous hydrogen would occupy a volume of about 11.1 cubic meters.
Is helium dense or less dense than water?
While the temperature and pressure a substance is under changes its density, it would take very high temperature and very low pressure on water and very low temperature and very high pressure on the hydrogen to make hydrogen more dense than water. So short answer, Hydrogen is less dense than water. While the temperature and pressure a substance is under changes its density, it would take very high temperature and very low pressure on water and very low temperature and very high pressure on the hydrogen to make hydrogen more dense than water. So short answer, Hydrogen is less dense than water.
Why atomic hydrogen is more reactive than hydrogen gas?
Hydrogen gas at standard temperature and pressure exists as diatomic molecules, and much of the chemical potential energy of atomic hydrogen has been evolved as heat along with forming the diatomic molecules.
Out of hydrogen water and oxygen which one has the highest density?
Oxygen has a higher density than hydrogen. At room temperature and pressure, oxygen has a density of approximately 1.43 grams per cubic centimeter, while hydrogen has a density of about 0.0899 grams per cubic centimeter.
Does the nuclear fusion occurs at the surface of the sun?
Fusion takes place in the core, where the temperature and pressure are much higher, which is necessary for fusion.
How much volume would a kilogram of gaseous hydrogen take up?
At standard temperature and pressure conditions, 1 kilogram of gaseous hydrogen would occupy a volume of about 11.1 cubic meters.
Why ammonia gas liquefies?
Ammonia gas liquefies when it is exposed to high pressure and low temperature. By increasing the pressure and decreasing the temperature, the ammonia gas molecules come closer together, reducing their kinetic energy and causing them to form a liquid state.
Is hydrogen less dense than air?
Yes, much lighter. The density of hydrogen is 0.08988 grams per litre, at standard temperature and pressure at sea level. The density of air is 1.22521 grams per litre, at the same temperature and pressure.
How much hydrogen gas can be stored in a 1lb cylinder tank?
A 1 lb cylinder tank can store approximately 0.109 cubic feet of hydrogen gas at standard temperature and pressure.

Is hydrogen a solid at 20 degrees?
Hydrogen becomes a solid at -434.5 degrees Fahrenheit
Out of hydrogen water and oxygen which one has the highest density?
Oxygen has a higher density than hydrogen. At room temperature and pressure, oxygen has a density of approximately 1.43 grams per cubic centimeter, while hydrogen has a density of about 0.0899 grams per cubic centimeter.
How is hydrogen stored in a Rocket?
Hydrogen is stored in liquid form in a tank, at low temperature. It would not be practical to store it as a gas, since it would take up too much space, or if sufficiently compressed, would have an excessively high pressure.
How much heat does it take to melt 3 kg of helium?
Helium is a gas at room temperature and pressure, so it does not melt. Instead, it turns into a liquid at extremely low temperatures (-268.9°C or -452°F). The amount of heat required to liquefy 3 kg of helium would depend on how much of it is in gas form and the specific heat capacity of helium at that temperature.
How much temperature hydrogen bomb can create?
10s of millions of degrees.
Why is it unsafe to much hydrogen gas without testing?
Hydrogen is an explosive gas in contact with oxygen and at high temperature.
