Hydrogen is a gas or liquid
WebAt normal room temperature, hydrogen is a gas. Hydrogen becomes a liquid at very low temperatures, around -425 degrees F or so. Liquid hydrogen is sometimes used for … WebThe heat of evaporation per unit mass of liquid hydrogen is about the same as for methane or propane, whereas it is much less per unit liquid volume. This feature and the greater temperature difference with the environment will cause pools of liquid hydrogen to evaporate faster than those of the other liquids.
