There are many ways to identify when a physical change has occurred. This can be done by recognizing reversible changes or eliminating chemical changes.
Physical changes involve state changes in matter and energy. These changes cause the matter to change form, but no new material is generated. Matter may alter in size, shape and color. When substances are combined but do not chemically react, physical changes take place.
A physical change can be recognized if it is reversible, especially if it involves a phase transition. For instance, if water is frozen into an ice cube, it can be melted back into water.
Sometimes eliminating the potential of a chemical transformation makes it easier to spot a physical change. There may be a number of signs that a chemical reaction has taken place.
