What is the definition of chemistry?

O The study of chemicals, which are compounds made of atoms and molecules
O The branch of science arising from the study of the physics of the atom
O The study of matter and the transformations it can undergo
O The applied science of matter and energy

Answer 1

Chemistry is the study of matter and its transformations at the atomic and molecular level.

Step-by-step explanation:

Chemistry is the study of matter and the transformations it can undergo. It focuses on the composition, structure, properties, behavior, and interactions of substances at the atomic and molecular levels. Through experiments, observations, and calculations, chemists investigate how different substances interact with each other and how they can be transformed into new substances. For example, they study the reactions between chemicals, the formation of new compounds, and the energy changes that occur during these processes.
