Classify each change as physical or chemical. Instead of looking at isolated examples, students evaluate multiple types of changes and apply clear criteria to determine whether new substances form or if the material keeps its original Feb 17, 2021 路 21. Chemical When analyzing various processes, we can classify them into either a physical change or a chemical change. A physical property can be observed directly or measured without changing the chemical identity of the substance (ex: mass, volume, shape). | Chemical/Physical Properties & Changes | | Key Concepts and Summary | Glossary | End of Section Exercises | Classify each of the changes as a physical change or a chemical change.
