Chemical vs. Physical Processes
Physical Processes
- Changes in Intermolecular Forces (IMFs)
- Properties change but composition remains the same
- e.g. phase changes and formation or separation of mixtures
Chemical Processes
- Involves the breaking and/or formation of chemical bonds
- Substances transform into other substances that may have different properties
- Temperature changes, light emittiance, precipitation or color changes are indications of chemical changes
Gray Area
- Dissolving salts in water involves breaking ionic bonds and creating ion-dipole interactions
