All matter can change from one form to another,
either physical or chemical.
A physical change in a substance doesn’t
change what the substance is; for
example, breaking a pencil, making orange
juice, boiling water, cutting paper, breaking
a glass, ice melting.
A chemical change in a substance produces a new substance with
different properties; for example, iron rusting, burning a piece of
wood, lighting a match, frying an egg, baking a cake.
