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.
Yes, argon is often used in rockets as a propellant or as a pressurant gas. It can be used for purposes such as pressurizing fuel tanks, providing a buffer gas in propulsion systems, or as a coolant in certain applications.
Liquid oxygen and liquid hydrogen are used as rocket fuel, oxygen gas is used by the astronauts to breath.
yep
hot gas
Other than rockets that use solid propellants or liquids (hydrazine, kerosene), large multi-stage rockets can be fueled with liquid hydrogen and liquid oxygen. The frigid liquid form is used because it provides a greater volume of propellant than simply pressurized gas. The more fuel it has, the faster and higher a rocket can go.
Gas generators are used to produce enormous amounts of energy. Therefore, they are used when there is need for such energy in cases like rockets launch or other similar take offs.

At various times they all used rockets, however the Katyusha rockets used by the USSR were popular, common and effective.
The propellant used in XIPS (Xenon Ion Propulsion System) rockets is Xenon gas. Xenon is ionized and accelerated using an electric field to generate thrust in these electric propulsion systems.
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 and their motors improve all the time.
Rockets, help us today because they can take us to space which is miles away from Earth. We don't use space shuttles today because they use up all their gas really quickly and it takes a long time to get to space by space shuttles so instead of space shuttles we have rockets that help us today to get to space.
