A physical change is a change to the physical

as opposed to chemical

properties of a substance.

They are usually reversible.

The physical properties of a substance include such characteristics as shape (volume and size), color, texture, flexibility, density, and mass.

Examples of Physical Changes are:

• An ice cube melting into water in your drink.
• Freezing water to make ice cubes.
• Boiling water evaporating.
• Hot shower water turning to steam.
• Steam from the shower condensing on a mirror.

A chemical change happens when one chemical substance is transformed into one or more different substances, such as when iron becomes rust.

A chemical change is different from a physical change, which doesn't rearrange atoms or molecules and produce a completely new substance.

Examples of Chemical Changes:

• Burning wood.
• Souring milk.
• Mixing acid and base.
• Digesting food.
• Cooking an egg.
• Heating sugar to form caramel.
• Baking a cake.
• Rusting of iron.
