There are many example of mixing chemicals and not observing any chemical reaction. Physical changes include transitions from one state to another, such as from solid to liquid or liquid to gas. Examples of chemical changes include, rusting, fire, and overcooking. When substances are combined, they may form a mixture, in which the individual substances retain their chemical properties, or they may form a chemical reaction, in which a new substance with its own chemical properties is created. All physical changes are reversible and their mass does not change. When added to water, the liquid dishwashing soap reduces the surface tension of the solution, which makes it possible to form bubbles.
