Question

The important use of cryogenics is cryogenic fuels. What do you mean by cryogenicfuels?

Answer 1

A cryogenic rocket engine is a rocket engine that uses a cryogenic fuel or oxidizer, that is, its fuel or oxidizer (or both) are gases liquefied and stored at very low temperatures.

Answer 2

Answer:

important use is as fuel in Spaceships .

Explanation:

Cryogenics is the scientific study of materials and their Production and behavior at very low temperatures.

This word is originated from the Greek

cryo, which means "cold",

and genic, which means "producing"

cryogenic fuels  are used in machinery that operates in space (e.g. rocket ships and satellites) because ordinary fuel cannot be used there, as environment does not supports combustion there.

Cryogenic fuels are fuels that require storage at very low temperatures in order to maintain them in a liquid state.

Cryogenic fuels generally constitute liquefied gases
