Hydrogen State Gas or Liquid

"On the State of Hydrogen"

Hydrogen is the lightest and purest in the world. Its state is either gas or liquid, both of which are related to the environment it is in.

Under normal temperature and pressure, hydrogen is in a gaseous state. Its nature is lively, light and floaty, and it can rise rapidly in the air. It is formless in view, tasteless in smell, and burns in the face of an open flame. It is explosive, and its power is very strong. Because of its simple molecular structure, it is only composed of two hydrogen atoms, and the number of electrons is small, it is easy to combine with others. This gaseous hydrogen also has the properties.

If it is cooled and pressurized to a considerable extent, hydrogen can form a liquid state. The color of liquid hydrogen is light blue, crystal clear and transparent, like the spiritual liquid in the sky. Its density is greatly increased compared with that of the gaseous state, and it contains huge energy. It is often used by the genus of aerospace as a source of power to help aircraft break through the sky and travel in the sky. Because of the high energy density of liquid hydrogen, the combustion product is only water, which is clean and harmless, and this liquid hydrogen has advantages.

The state of hydrogen, or gas or liquid, has its own uses. Knowing this principle, making good use of it will be of great benefit to the advancement of science and technology and the benefit of people's livelihood.
