What is the definition of chemical energy?

Chemical energy is defined as the energy that arises from the forces that bind the atoms together in a molecule. This form of energy is related to the arrangement of electrons and the bonds that connect different atoms within a molecule. When these bonds are formed or broken during a chemical reaction, energy is either absorbed or released. For instance, in a combustion reaction, the chemical energy stored in fuel is released in the form of heat and light when the molecules react with oxygen.

Understanding this concept is crucial in various applications, including combustion engines and other mechanical systems where fuel is transformed into usable energy. The other options refer to different types of energy; for example, the movement of objects pertains to kinetic energy, while energy based on an object's position describes potential energy. Energy released during a phase change is more related to the transition between states of matter, such as solid to liquid. Therefore, option B accurately captures the essence of chemical energy as it specifically describes the forces at work within molecules.
