Chemistry is the study of matter, its properties, and interactions with energy. Chemistry is related to other sciences like physics and biology and uses the scientific method. Studying chemistry helps us understand cooking, digestion, and even how medications work.
Chemistry studies how matter and energy interact, with atoms and molecules forming through chemical reactions. Chemistry is everywhere, as it involves everything you touch, taste, or smell in daily life. Chemistry is a hands-on and real-world science, providing tools to solve real problems and make new products.
General chemistry topics include things like atoms and molecules, how substances react, the periodic table, and the study of different compounds.
