Mass, volume, melting point and boiling point are all examples of physical properties because...

• the substance(s) remain the same when observed.

• the substance(s) changes into a new substance when observed

• the Atoms rearrange to form new substance(s). Different arrangement = Different substance

• the atoms are still arranged the same way. Same particles = same substance

Flammability, reactivity, and toxicity are all examples of chemical properties because...

• the substance(s) remain the same when observed.

• the substance(s) changes into a new substance when observed

• the Atoms rearrange to form new substance(s). Different arrangement = Different substance
