Which of the following could act as a propellant for rockets?(a) Liquid oxygen + liquid argon(b) Liquid hydrogen + liquid oxygen(c) Liquid nitrogen + liquid oxygen(d) Liquid hydrogen + liquid nitrogen
Answers
The answer of your question is
Option-C
Answer:
(b) Liquid hydrogen + liquid oxygen is the correct answer.
Explanation:
The principle of rocket propellant depends on the following laws
1) Newton's third law of motion.
2) law of conservation of momentum.
There are three types of rocket propellants
1) liquid propellant
2) solid propellant
3) hybrid propellant
Liquid propellant rocket engines burn two separately stored liquid chemicals, fuel and an oxidizer to produce the thrust.
The typical example is liquid hydrogen and liquid oxygen which is a cryogenic type of propellant purl or oxidizer.
A cryogenic propellant is one that uses cold liquefied gases as the fuel and the oxidizer.
They require special insulation properties.
Hence
(b) Liquid hydrogen + liquid oxygen is the correct answer.
