Solution:
Concept- Study of matter and its states, study about properties, composition, and structure is called chemistry. Anything with mass and space is considered to be the matter. The matter is capable of changing when exposed to various conditions and surroundings.Any type of matter, such as a solid, liquid, or gas, is possible. Chemistry and physics are the two subfields of physical science.
Chemistry is the study of energy and matter (solid, liquid, or gaseous) at the atomic and molecular levels. The study of matter and its properties is known as chemistry (physical and chemical).
Chemistry can be defined as the study of the composition, structure, and properties of matter. It also focuses on the reactions that transform one type of matter into another.
Hence, the correct answer is option 1.
