chemical propellants

Chemical propellants are substances that produce a controlled release of energy through chemical reactions, typically combustion or decomposition. When ignited, they rapidly generate hot gases and pressure, which are expelled through a nozzle to produce thrust. This process propels rockets or missiles by converting chemical energy directly into mechanical motion. The most common types include liquid and solid propellants, each designed for different applications, offering reliable and efficient means to generate the force needed for space travel, military defense, or industrial uses. Their effectiveness depends on the energy stored in their chemical bonds and how efficiently that energy is converted into movement.
