What is physical and chemical change
When matter changes it observable properties, we can say it has undergone a physical change. Physical change is a type of change where the physical properties of matter change. A change of state of matter, change in color, odor, solubility, etc. all are examples of physical change.
Different substances have different chemical property. According to this property, substances show variation in their reactivity.
Chemical change is a type of change where the chemical properties of matter change. It is commonly called a chemical reaction. A chemical reaction results in a new product. During a chemical change, bonds between the molecules break and the composition of the substance change.
