The Properties of Matter

2. What is Matter? Matter is anything that has Mass and Volume
Mass is the amount of matter an object contains.
Units: grams (g), kilograms (kg)
Volume is the amount of space an object takes up.
Units: liters (L), milliliters (mL), cubic centimeters (cm3)

4. Physical vs. Chemical Properties

5. Physical Properties
Physical properties can be observed or measured without changing the identity of the matter.
Examples:
Color
Odor
Mass
Volume
Density (Density = Mass/Volume)
State – Solid, Liquid, or Gas?
Malleability – Can I flatten it?
Ductility – Can I stretch it into a thin wire?
Solubility – Can I dissolve it in something?
Thermal Conductivity – Does it carry heat?

7. Chemical Properties
Chemical properties describe a substance’s ability to change into a new, different substance.
Examples:
Flammability – Does it burn?
Reactivity – Does it react when mixed?

9. Characteristic Properties
Characteristic properties are always the same, whether the object is large or small.
Characteristic properties can be physical or chemical.
Examples:
Density
Solubility
Reactivity

10. Physical Changes
In a physical change, a physical property changes, but the identity of the substance does not change.
Physical changes are sometimes easy to undo
Examples:
Melting ice or boiling water
Ripping paper into pieces
Dissolving sugar into water

12. Chemical Changes
In a chemical change, a substance changes into a different substance.
Chemical changes are usually difficult to undo.
Examples:
Burning wood or “snakes”
Spoiling milk (curdling)
Rusting metal
