Concept explainers
Interpretation:
The term chemistry is to be defined.
Concept introduction In ancient times, there were people known as alchemists who tried to change substances into other substances such as gold. These alchemists were early chemists. Their research gave birth to a new field of study called chemistry.

Answer to Problem 2E
Chemistry is the study of substances in the world around us. It is the study of matter, their properties and how matter can be changed into new substances.
Explanation of Solution
The modern study of chemistry came into existence due to the efforts made by alchemists. They invented useful tools and discovered several important laboratory techniques.
Chemistry is the study of matter. It deals with substances that make up a matter, how these substances behave and how they can be changed into new substances. It is the study of changes in the properties of matter. Chemistry investigates how matter can be changed and helps us to understand the logic behind such changes.
Chemistry describes the physical and chemical properties of a matter and gives hypothesis to explain the changes that may occur in matter due to some procedures.
Chemistry is the study of substances that make up matter. It is the study of properties of matter and how matter can be changed into new substances.
