Physical and Chemical Changes
A physical change is a change to matter in which no new matter is formed. Physical changes may cause matter to look different. Changing temperature can make matter change. But in a physical change, no new matter is formed.
A chemical change is when the particles in the matter change and new matter is formed. Cooking food makes new kinds of matter. Flour, eggs, milk, and oil turn into pancakes. The pancakes will never be just flour, eggs, milk, and oil again. Burning and rusting are chemical changes.
