Hydrogen is a gas.
The only method that can cause this gas to become liquid is pressure.
Hydrogen is an element. You cannot change one element to another without a nuclear reaction. However, hydrogen gas can be changed to liquid hydrogen by compressing and cooling it. Liquid changes to gas by releasing pressure, and warming it.
no, it is chemical.
Hydrogen is a gas at room temperature.
Hydrogen gas become a liquid at very low temperature; and after we can obtain solid hydrogen.
At room temperature hydrogen is a gas.
It is a gas and a liquid
If one chemically reacts oxygen gas and hydrogen gas, any liquid produced is water.
yes, hydrogen can be found as a solid liquid and a gas within Jupiter
The change from liquid or solid into vapor. Note that there are technically still hydrogen bonds while in the gas phase, but they're not as important (unless at a high pressure and/or low volume).
Hydrogen is not a liquid at room temperature. H2 changes from gas to liquid state at about -253oC .
The change from a liquid to a gas is evaporation.
No Hydrogen is a gas and when frozen turns into a solid
