"On the State of Hydrogen"
Hydrogen is the lightest and purest element between heaven and earth. Its state is often related to the change of temperature and pressure.
Under normal temperature and pressure, hydrogen is a gas. Looking at its quality, it is colorless and odorless, light and floating, and difficult to dissolve in water. Because its molecules are flexible and widely spaced, it is in the shape of a gas state, free to float and amorphous.
If the temperature is cooled to an extremely low level, about minus 250 degrees Celsius, near absolute zero, the molecular kinetic energy of hydrogen decreases sharply, and mutual attraction gradually becomes apparent, and then it condenses into a liquid. At this time, the hydrogen liquid is clear and has good fluidity, so it needs to be in an extremely cold environment to survive.
As for solid hydrogen, more stringent conditions are required. When the temperature drops to a lower level and high pressure is applied, the hydrogen molecules can be tightly arranged to form a solid structure. Solid hydrogen is like an ice crystal, but it has unique physical properties. Its formation and maintenance depend on extreme temperature and pressure environments.
In short, the state of hydrogen varies with temperature and pressure. Gaseous states are commonly found in ordinary situations, while liquid and solid states exist in special environments. This is the wonder of nature and the wonder of material changes.
