Answer 2

Answer:

Physical change :

A physical change takes place due to change in the parameters such as temperature, pressure. Often a physical change is reversible. The composition of matter remains the same in a physical change.

Chemical change :

A chemical change is a process in which some substances undergo bond breaking and are transformed into new substances by formation of new bonds. If the composition of matter changes during a process then it is called a chemical change.
