What is a proportiant?

Answer 1

A propellant is a substance that produces thrust when it undergoes a rapid chemical reaction, typically used in rocket engines and other propulsion systems. It can exist in solid, liquid, or gas forms and is often a combination of fuel and an oxidizer. When ignited, the propellant generates high-pressure gases that are expelled to propel the vehicle. Common examples include liquid hydrogen and oxygen in rockets or solid composite propellants used in missiles.
