Give examples where physical change can be observed.

Grinding, tearing, cutting are examples of physical changes. There is no change in the chemical composition in these processes.

Physical change

Physical changes involve states of matter and energy. No new substance is created during a physical change, although the matter takes a different form. Some examples include:

  • Crushing a can
  • Melting of an ice cube
  • Boiling water
  • Mixing sand and water
  • Breaking a glass
  • Dissolving sugar and water
  • Shredding paper

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.
