Answer:
chemical change:
A chemical change is a type of change where the chemical properties of matter change. It is commonly called a chemical reaction. Different substances have different chemical property. According to this property, substances show variation in their reactivity.
E.g: burning, cooking, rusting, and rotting
physical change:
A physical change is a type of change in which the form of matter is altered but one substance is not transformed into another. The size or shape of matter may be changed, but no chemical reaction occurs.
E.g: boiling, melting, freezing, and shredding
