Anotações:

• Matter is anything that takes up space and has mass

1. Molecules
   1. Solids

      Anotações:

      • Solids: The molecules are in a fixed position. Each molecule has enough energy to vibrate, but not enough to leave it's place.
   2. Liquids

      Anotações:

      • The molecules have enough energy to slide and roll over and around each other. They are not fixed in position, but they cannot break away from each other
   3. Gasses

      Anotações:

      • The molecules have enough energy to separate completely from each other and move off in all directions
