Difference Between Physical And Chemical Change

2018-6-19  A chemical change is a permanent change. A Physical change affects only physical properties i.e. shape, size, etc. Chemical change both physical and chemical properties of the substance including its composition: A physical change involves very little to no absorption of energy. During a chemical reaction, absorption and evolution of energy take place.
