chemistry
Chemistry is a field of natural sciences that studies the nature, composition, structure, change and accompanying changes in energy of matter. Physics is also a study of matter, but unlike physics which deals with the motion, energy, thermal, electrical, optical, and mechanical properties of an object, including both elements and compounds, and builds a unified theory from these phenomena, . Chemistry provides a way to synthesize new materials for specific purposes by using already existing materials, which offers several benefits such as crop production, treatment and prevention of disease, increased energy efficiency, and reduced environmental pollution.
