Physical change is a change in matter that does not create a new substance. The material keeps its original identity even though its form may change. Examples include melting ice, freezing water, or breaking an object. These changes can affect shape, size, or state.

Physical changes are found in everyday processes on Earth, such as weather changes and handling materials. Many physical changes can be reversed, such as turning ice back into water. Physical changes are part of how matter can change form.
