While investigating physical properties, the change is described as a change of states of matter or appearance of the substance while still being the same substance. Chemical changes in matter changes the substance very differently than physical change. As a result, chemical change changes the substance's chemical and even physical properties as it gets mixed with another chemical.Summary: There are two types of changes in matter: Physical Changes and Chemical Changes. Physical Changes are often when states of matter changes, but does not remove or form new substances. This change can also be reversible and does not absorb or release energy. Molecules don't break apart or rearrange, instead spacing of the molecules changes. Chemical Changes occur when new substances are formed and when molecules are separated, rearranged into new molecules. This change is difficult to reverse and energy can be absorbed and released. It can also be identified from it's color, odor, texture, release of gas, or changes of temperature and state.
