What are the similarities of physical and chemical changes?

Answer

When matter undergoes a physical change, it does not permanently affect molecular structure in the same way that a chemical change does. A physical phase change alters the state of matter, but does not rearrange the atoms at the molecular level. An example of a physical change is ice reverting back to water at room temperature. After undergoing a chemical change, there may be few similarities between the resulting and original substance, such as when the body digests food for energy and nutrients.
