Question

what is chemical and physical change
give some examples ​

Answer 1

CHEMICAL CHEMISTRY

A chemical change is a change of materials into another, new materials with different properties and one or more than one new substances are formed. It results when a substance combines with another to form a new substance (synthesis or either decomposes to form more substances).

PHYSICAL CHANGES

When matter changes its observable properties, we can say it has undergone a physical change.

During a physical change, neither the composition nor the chemical nature of matter is changed.  During this change, molecules rearrange themselves without affecting the internal composition. A physical change doesn’t affect the chemical property.
