At What Pressure Hydrogen Liquid
On the pressure of hydrogen liquefaction
Hydrogen is the lightest and cleanest gas. If you want to make it into a liquid, there must be specific pressure and temperature conditions.
Looking at the physical properties, the gaseous state of hydrogen is light, its molecules are agile and uninhibited, and often move at high speed. To make it condense into a liquid, you must control its movement and shrink its distance. Temperature and pressure complement each other to control the state change of hydrogen.
When the temperature is set, the increase or decrease of pressure depends on whether the liquid of hydrogen is formed or not. When heavy pressure is applied, the molecular spacing gradually fades and the interaction gradually intensifies. When the pressure reaches a certain critical value, the attractive force between the molecules of hydrogen is enough to restrain it and make it gather into a liquid.
It is not easy to determine this critical pressure. The difficulty of covering the experiment and the difference in the environment can lead to the difference in results. However, there are many lessons from previous research. After repeated trials and errors, accurate measurement, a little clue.
At extremely low temperatures, the pressure required for hydrogen to liquefy is quite considerable. Only in the high pressure environment can the molecules of hydrogen converge their fugibility and turn gas into liquid. The number of pressures varies slightly depending on the experimental method and the environment, but is generally within a certain range.
Therefore, in order to make hydrogen into a liquid, the control of pressure is crucial. Knowing this pressure is of great benefit to the hydrogen production liquid in industry and the exploratory nature of scientific research. Only by knowing it and knowing why it is can we make good use of the wonders of hydrogen and contribute to the progress of the world.
