Interpretation:
The process needs to be determined which changes the matter.
Concept introduction:
Chemistry deals with the different processes which occur in surrounding and is directly or indirectly related with each other.
Different changes taking place in the environment can be physical and chemical on the basis of change in physical state and chemical composition of the matter.
Physical changes are related to change in the physical state of the substance whereas the chemical change is associated with change in chemical composition that results the formation of new chemical substance/s.

Answer to Problem 1TAI
In a chemical change, the chemical composition of substance changes therefore it forms a new substance during the reaction.
Explanation of Solution
In a physical change, the physical
An example of a physical change is represented as follows:
In a chemical change, the chemical composition of substance changes therefore it forms a new compound during the reaction.
The example of a chemical change is represented as follows:
Here, a new substance AB is formed from A and B thus, it is a chemical change.
In a chemical change, the chemical composition of substance changes therefore it forms a new substance during the reaction.
