Study Notes
Properties of Matter
- Properties of matter can be physical or chemical
- Physical properties can be observed or measured without changing the substance's chemical composition
- Examples: mass, density, color, volume
- Chemical properties reflect how a substance will react with other substances
- Examples: reactivity, flammability, pH
Physical Properties
- Solubility describes the ability of a substance to dissolve in a solvent
- Sugar is highly soluble in water, while sand is practically insoluble
- Density is a measure of how much mass is contained in a given volume
- Iron has a higher density than water, which is why it sinks
- Hardness is a measure of a substance's resistance to scratching or indentation
- Diamonds are known for their hardness
- Volatility describes how easily a substance evaporates at a given temperature
- Highly volatile substances evaporate quickly, while less volatile substances evaporate slowly
- Ductility is the ability of a substance to be drawn into a wire without breaking
- Many metals are ductile
- Malleability is the ability of a substance to be hammered or rolled into thin sheets without breaking
- Metals are commonly malleable
- Viscosity is a measure of a fluid's resistance to flow
- Honey is more viscous than water
- Heat conductivity is a measure of a substance's ability to transfer heat energy
- Metals are good heat conductors
- Electrical conductivity is a measure of a substance's ability to conduct electricity
- Silver, gold, and copper are excellent electrical conductors
Chemical Properties
- Flammability is the ability of a substance to catch fire and burn
- Reactivity describes the tendency of a substance to undergo chemical reactions
- Sodium reacts violently with water
Intensive vs Extensive Properties
- Intensive properties depend only on the type of matter, not the amount
- Examples: density, color, melting point, electrical conductivity
- Extensive properties depend on the amount of matter present
- Examples: mass, volume, length
