In a physical change the appearance changes but the substances does not

1 answer

That's correct! In a physical change, the form or appearance of a substance changes, but its chemical composition remains the same. This means that the substance retains its inherent properties, and no new substances are formed. Common examples of physical changes include:

  • Melting of ice into water
  • Boiling water into steam
  • Dissolving sugar in water
  • Breaking a glass

In each of these examples, while the state or appearance of the material may change, the molecules and their chemical structure remain unchanged.
