What branch of science studies the composition of matter and its properties?

Chemistry is the branch of science that studies the composition, structure, properties, and transformations of matter. It explores how substances interact, combine, and change during chemical reactions. Chemistry bridges physics and biology, explaining phenomena from molecular bonding to biological processes. It is divided into subfields such as organic, inorganic, physical, analytical, and biochemistry. Chemists investigate elements and compounds to develop new materials, medicines, fuels, and technologies that improve human life. Understanding chemistry helps explain everyday occurrences, from digestion to combustion, and plays a crucial role in advancing industries like pharmaceuticals, agriculture, and environmental science.
