Chemistry is science which teaches the nature and property of all matter by their analysis and combination. Chemistry is the study of matter and its interactions with other matter. Anything made of matter is therefore a chemical. Any liquid, solid, gas. Chemistry is closely related to physics and to biology. Knowledge of mathematics is an essential tool for the study of chemistry.
The main branches of chemistry include organic, inorganic, analytical, and physical chemistry. Specialized areas include, among others, spectroscopy, geochemistry, and astrochemistry.
