Explanation:-

Physical change: A change that alters some specific property of matter without any change in the composition of its molecules is called a physical change.

Chemical change: A change that alters the specific properties of a substance by bringing about a change in its molecular composition, followed by a change in its state, is called a chemical change.

  • During the physical and chemical change, the energy is released and absorbed in the form of sound energy, heat energy, heat, and light energy.
