Chemical Energy

Chemical energy is the potential energy stored in the chemical bonds between atoms and molecules. In the context of space and astronautical engineering, chemical energy is often used to power rockets and spacecraft. Chemical reactions, such as the combustion of rocket fuel, release energy in the form of heat and gas, which propels the spacecraft forward. The amount of chemical energy stored in a fuel is known as its energy density, which is an important factor in determining the efficiency and range of a spacecraft. Chemical energy is also used in batteries to power spacecraft systems and instruments.
