Liquid Oxygen and Liquid Hydrogen are used as rocket fuel as it is the most effecient way to thrust rockets into space, Liquid Nitrogen is not transported into space.
It is used as oxidant in the rockets.
nitrogen is used for fertilizer
nitrogen is used for experiments like: trying to turn a liquid into a solid nitrogen can do that for you
nitrogen in the soil is used by both plants and animals.
Rockets typically use Liquid oxygen and liquid hydrogen for fuel. I suspect this is what you are asking. I know of no rocket that uses liquid nitrogen.
they are hydrogen, nitrogen and oxygen
Liquid Oxygen and Liquid Hydrogen are used as rocket fuel as it is the most effecient way to thrust rockets into space, Liquid Nitrogen is not transported into space.
Common elements pulled from the atmosphere used in spaceflight are oxygen, hydrogen, and nitrogen. Nitrogen isn't used for propellant, its actually used prior to ignition to purge the engines of anything that may inhibit or react during ignition.
rockets are used in many diffrent ways now
It is used as oxidant in the rockets.
The primary performance advantage of liquid propellants is due to the oxidizer. Several practical liquid oxidizers (liquid oxygen, nitrogen tetroxide, and hydrogen peroxide) are available which have better specific impulse than the ammonium perchlorate used in most solid rockets, when paired with comparable fuels.
At various times they all used rockets, however the Katyusha rockets used by the USSR were popular, common and effective.
Some rockets are used for space travel and others are used for war. some other rockets are hand made like baking soda rockets. Rockets carry satellites and astronauts into space, missiles, distress beacons, even pyrotechnics (fireworks) for amusement.
Chinese people used the rockets as weapons in wars. They also used them for fireworks for special celebrations. They called the rockets "arrows of fire". Rockets now, are much BIGGER for the rockets used for war in china. Alison Chia Hui Xin
rockets were used for military use and fireworks
Rockets and their motors improve all the time.
