The study of the composition, structure, and properties of matter; the processes that matter undergoes; and the energy changes that accompany those processes best describes the science of chemistry.
Chemistry is a branch of Natural Sciences that studies matter, its properties, constitution, transformations and the energy involved in these processes.
Matter is the main object of study in Chemistry and can be defined as everything that occupies space and has mass, that is, the entire material world around us and even ourselves.
