Summary: Physical and Chemical Properties
Physical Properties
Physical properties are characteristics of a substance that can be observed or measured without changing its chemical identity. These properties describe how a substance looks or behaves in the physical world.
Examples:
- Color
- Shape
- Mass
- Melting point
- Boiling point
- Density
- Solubility
- Magnetism
- State of matter (solid, liquid, gas)
Chemical Properties
Chemical properties describe how a substance interacts with other substances or how it changes into a new substance. These properties can only be observed during a chemical reaction.
Examples:
- Flammability
- Ability to rust
- Reactivity with acids or bases
- Ability to decompose
- Tarnishing
- Ability to ferment or sour
