How hydrogen can be made into a liquid?

Answer 1

To turn hydrogen to a liquid, you have to either lower the temperature or increase the pressure or both. At one atmosphere (the air pressure at sea level) hydrogen liquefies at 20 degrees Kelvin (about -423°F).

Any gas can be turned into liquid by cooling it down under high pressure. with a pressure engine

Answer 2

Hydrogen can be turned into a liquid through a process called liquefaction, which involves cooling gaseous hydrogen to extremely low temperatures below its critical point of -252.87°C. At this temperature, hydrogen transitions from a gas phase to a liquid phase. The liquid hydrogen is then stored and used in various applications such as rocket propulsion and superconducting magnet cooling.

Answer 3

because of the chemical reaction of the pollution to the earth on the residua levels to the world.

Answer 4

If you combine hydrogen with oxygen, you can get a liquid called water, which can also be written as H20. This means that for every 2 hydrogen atoms, there is 1 oxygen atom.

Answer 5

Cool it down to -427 degrees Fahrenheit, and keep it under pressure.
