* Flammability: This describes how easily a substance burns, a chemical change.
* Reactivity: Indicates how readily a substance reacts with other substances, involving chemical transformations.
* Corrosion: Describes the process of a substance being chemically attacked by its environment, like rusting.
* Toxicity: The ability of a substance to harm living organisms through chemical interactions.
* Digestion: The breakdown of food into simpler molecules by chemical reactions in the body.
* Photosynthesis: The process by which plants convert light energy into chemical energy, changing the substance of the plant.
Key Takeaway: Physical properties are inherent and can be observed without changing the substance's chemical makeup. Non-examples involve changes in the chemical composition of a substance.
