Explanation:

Chemistry is a branch of science that deals with different substances in recognizing the matter present in them.

For example, chemistry deals with states of matter like solid, liquid or gas.

Also, it tells us about how different substances present in nature react or what is their composition and properties.

Basically, chemistry helps us knowing nature of a matter and how it can be transformed.

Thus, we can conclude that chemistry is the study of matter and its transformation.
