Answer:

  • Physical change : The change occurring in the physical properties of a substance like change in shape, size, etc. It is usually a reversible process.
  • Chemical change : The Change occurring in the chemical properties of a substance like change in the chemical composition of substance.

Explanation:

  • Particles rearrange into new combination, forming new substances = Chemical change
  • There is no change in the chemical properties of the substance = Physical change
  • Particles retain their composition and identity = Physical change
  • The chemical properties of the substance change = Chemical change

The change resulting in the formation of the new substance is called a chemical change. The chemical properties alter in this type of change. Thus, options A and D are chemical changes.

What are chemical changes?

A chemical change has been defined as the rearrangement of the older particles and molecules into new combinations resulting in product formation. The new substance produced has different chemical properties. Hence, options A and D are correct for chemical change.

The physical change has been characterized by no change in the chemical property and composition of the substance produced. The product retains its identity and is a reversible alteration. Hence, options B and C are correct for physical change.

Therefore, options A and D. new substance with varied chemical composition is a chemical change.
