Study Notes
Properties of Matter
- All kinds of matter have two common properties: occupying space (having a volume) and having mass
States of Matter
- There are three states of matter: solid, liquid, and gas
- Any substance can exist in these three states depending on the pressure and temperature
- Changing the temperature and/or pressure can change the state in which a substance exists
States of Matter
- Solids have a fixed volume, high density, and a definite shape, and do not flow.
- Liquids have a fixed volume, average to high density, no definite shape, take the shape of their container, and generally flow easily.
- Gases have no fixed volume, expand to fill their container, have low density, no definite shape, take the shape of their container, and flow easily.
Thermal Properties
- Increasing the temperature causes an increase in volume (expansion).
- Decreasing the temperature causes a decrease in volume (contraction).
Gas Properties
- Temperature affects gases more than liquids and solids.
- The volume of a gas can be easily reduced at a fixed temperature by increasing the pressure, making gases easily compressible.
