what is the definition of chemical change?

• any change that results in the formation of new chemical substances. 
• changing clothes
• matter cannot be created or destroyed, only change form
• changes affecting the form of a chemical substance, but not its chemical composition.

• rusting
• changes affecting the form of a chemical substance, but not its chemical composition.
• any property that is measurable, whose value describes a state of a physical system
