Cryogenic Fluids and Liquefied Gas Properties

Cryogenic properties as density, boiling points and heat of evaporation for fluids like hydrogen, methane, oxygen, nitrogen, fluorine and helium.

Cryogenic services involves the handling of liquefied gases like helium, hydrogen, methane, nitrogen, oxygen and fluorine in temperatures between -150 oF to -450 oF.

The "cryogenic" properties of these materials can be summarized to:
