Four examples of physical changes in matter include: melting of ice into water, boiling of water into steam, freezing of water into ice, and shredding of paper. These changes are physical because they alter the form of the substance without changing its chemical composition. Each process can be typically reversed, returning the substance to its original state without any new substances being formed.

Questions and answers

  1. What is a physical change in matter?

    A physical change is a change in the form or appearance of matter without altering its chemical composition.

  2. How can you tell if a change is physical or chemical?

    A physical change can be reversed and does not produce new substances, while a chemical change forms new substances and is usually irreversible.

  3. Can physical changes be reversed?

    Yes, physical changes like melting, freezing, and boiling can often be reversed by changing conditions such as temperature.
