Document Summary

Introduction: energy is being perpetually transformed from one form to another. The study of changes in energy is studied through all fields of science and not limited to physics and chemistry. Chemical reactions are able to facilitate this transfer of energy by releasing or absorbing the energy in some form depending on the specific reactants and products ii. Energy can be classified as either potential or kinetic energy. Potential energy is defined as the energy due to the position or composition of an object. Kinetic energy is the energy of chemicals due to its motion iii. All chemicals have the potential to produce or absorb kinetic energy due to the nature of the bonds holding the reactants and products together. A chemical system is composed of the reactants and products being studied while the surroundings are all matter that is not part of the system but are affected by the system itself.
