The physical state of any element/molecule depends on the intermolecular interaction between hydrogen molecules and here this is only a fairly weak dispersion force, which is reasonable because the molecule is certainly non-polar, and has not many electron. The same situation pertains to dioxygen, and dinitrogen, in the air we breathe, in that their intermolecular forces are also weak, tho these are more involatile given that the extra electrons these gases possess result in greater intermolecular interaction.
Thus dihydrogen, dinitrogen, and dioxygen are ALL room temperature gases.
