what is the chemistry .And what is the physics ?
Answers
chemistry---the branch of science concerned with the substances of which matter is composed, the investigation of their properties and reactions, and the use of such reactions to form new substances.
physics--
the branch of science concerned with the nature and properties of matter and energy. The subject matter of physics includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms.
Chemistry and physics are branches of science that both study matter. The difference between the two lies in their scope and approach. Chemists and physicists are trained differently, and they have different professional roles, even when working in a team. The division between chemistry and physics becomes diffuse at the interface of the two branches, notably in fields such as physical chemistry, chemical physics, quantum mechanics, nuclear physics/chemistry, materials science, spectroscopy, solid state physics, solid-state chemistry, crystallography, and nanotechnology.
