Answer:
1.In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed. ... All chemical reactions are reversible although this can be difficult in practice.
2.A physical change is a change in the form or physical properties of a substance but not in its chemical composition. For example, processes of evaporation, condensation, solidification, melting, wetting and drying change the form of a substance. Heating and cooling change the temperature of a substance.
3.And you can reverse a physical change to recover all of the original matter, even if it doesn't look exactly the same
4.Chemical reactions turn food into fuel for your body, make fireworks explode, cause food to change when it is cooked, make soap remove grime, and much more. Exciting and entertaining chemical reactions pique interest in science.
