Yes, liquid hydrogen is also called liquefied hydrogen and also called cryogenic hydrogen. You can produce it my increasing the pressure (with cooling) until the gaseous hydrogen is liquefied.

Liquid hydrogen - the liquid state of hydrogen gas (H2)

Water - the liquid of H2O

Hydrogen - usually refer to hydrogen gas (H2)

Liquid nitrogen and liquid oxygen are two examples like liquid hydrogen in chemistry.

Dear

The liquid hydrogen is named as liquefied hydrogen and and is denoted by H2, where as water which is in liquid form is denoted by H2O

Thank you Sir @Mohd Pervez.

But is their any chemical difference between Hydrogen and liquid Hydrogen. The two are confusing me.
