Here's why:
* Matter: Chemistry focuses on the composition, structure, properties, and reactions of matter. This includes everything from the smallest atoms to complex molecules.
* Changes in Matter: Chemistry explores how matter changes its form and composition through chemical reactions, which involve the breaking and forming of chemical bonds.
While other branches of physical science like physics also deal with matter, their focus differs. Physics is more concerned with the fundamental laws governing the universe, such as motion, energy, and forces, while chemistry delves deeper into the specific interactions and transformations of matter.
