Chemical reaction
A change in matter that produces a new substance is called a chemical reaction. This involves the breaking and forming of chemical bonds between atoms to create different molecules with distinct properties.

(rusting iron)
This is called a change in the physical state of the substance. For example formation of ice from water is a change in the physical state of water.
During a physical change, the matter of what the substance is made out of doesn't change.

Because density is a "ratio".
a chemical change
A change in matter that produces one or more new substance is a chemical reaction. This is also known as a chemical change.
A chemical change in matter produces a new substance. A physical change, on the other hand, only alters the state or phase of matter without producing a new substance.
Nuclear and Chemical changes result in new substances.

This is called a change in the physical state of the substance. For example formation of ice from water is a change in the physical state of water.
When a substance changes from one state of matter to another it is called changing its state. Temperature changes are usually the main cause of this change.

A chemical change is a change in which a change of matter that produces one or more new substances is a chemical change.Unlike a physical change, a chemical change produces new substances with new and different properties. Examples of chemical changes are combustion,electrolysis, oxidation,and tarnishing, frying an egg, burning of wood, cutting a tree.
Physical property of matter
Physical changes result in a change in appearance or physical state without forming new substances, such as melting ice or breaking a glass. Chemical changes involve the rearrangement of atoms to form new substances with different chemical properties, like burning a piece of paper or rusting of iron.
