As a chemical expert with a deep understanding of the physical properties of elements, I can provide you with a detailed explanation about the state of hydrogen under various conditions.
Hydrogen, being the lightest and most abundant element in the universe, exhibits fascinating physical properties.
At standard temperature and pressure, hydrogen is indeed a gas. It is colorless, odorless, and has the lowest density of any gas at room temperature, which is approximately 0.08988 g/L. This low density is due to the fact that hydrogen molecules (H2) are very small and have weak intermolecular forces, allowing them to move freely and rapidly.
However, hydrogen's state can change significantly with temperature and pressure. When cooled to very low temperatures, hydrogen can become a liquid. The liquefaction of hydrogen occurs at a temperature of approximately -423.15 degrees Fahrenheit (-252.87 degrees Celsius) under one atmosphere of pressure. This is a critical point in the phase diagram of hydrogen, where the distinction between liquid and gas becomes less clear.
Liquid hydrogen is an important substance in various applications. It has a very high energy content by weight, which makes it an attractive fuel for rockets and spacecraft. The high energy density is due to the fact that hydrogen has the highest specific enthalpy of combustion of any common fuel. This is why it is used in the space industry for launching satellites and space probes.
Transporting and storing liquid hydrogen, however, requires special conditions. It must be kept at extremely low temperatures to prevent it from boiling off and turning back into a gas. This is typically done using cryogenic tanks that are well-insulated and equipped with cooling systems to maintain the low temperature.
In addition to its use as a rocket fuel, liquid hydrogen is also considered a potential energy carrier for the future. It can be produced from renewable energy sources through a process called electrolysis, where water is split into hydrogen and oxygen using electricity. This makes hydrogen a candidate for a sustainable and clean energy source.
Furthermore, the study of hydrogen in its various states is crucial for understanding fundamental principles of chemistry and physics. It helps scientists and engineers to develop new technologies and materials that can utilize hydrogen's unique properties.
In summary, while hydrogen is a gas at room temperature, it can be liquefied under certain conditions. Its ability to be used as a liquid is significant for various high-energy applications, particularly in the aerospace industry. The management of liquid hydrogen requires careful consideration of its cryogenic storage and transportation needs.

At 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 fuel in rockets, among other things, so yes, it can be transported and used as a liquid.
