Study Notes
Matter
- Matter is anything that has volume and mass.
- Volume is the amount of space something takes up.
- Solids, liquids and gases all have volume.
- Air is made up of gases, and takes up space.
States of Matter
- Matter exists in three states: solid, liquid, and gas.
Temperature and Volume
- The volume of matter changes with temperature.
- Heating matter usually causes an increase in volume.
- Cooling matter usually causes a decrease in volume.
- Gases change volume more easily than solids.
- They fill whatever container they are in.
- Gases expand when heated under constant pressure.
- Cooler gas usually has a smaller volume.
Mass and Inertia
- Mass is the amount of matter in an object.
- Objects with more mass are harder to move.
- Inertia is the tendency of an object to resist changes in motion.
- Objects with more mass have more inertia.
