  1. 1. A substance made up of atoms of two or more different elements joined by chemical bonds
  2. 2. The smallest unit of an element that maintains the properties of that element
  3. 6. Mass divided by volume
  4. 7. The state of matter in which the volume and shape of a substance are fixed
  5. 9. The total kinetic energy of a substance’s particles
  6. 11. A measure of low hot (or cold) something is; specifically, a measure of the average kinetic energy of the particles in an object
  7. 13. A measure of the amount in an object
  8. 15. A substance that cannot be separated or broken down into simpler substances by chemical means
  9. 16. A group of atoms that are held together by chemical forces; a molecule is the smallest unit of a compound that keeps all the properties of that compound

  1. 1. The change of substances from one physical state to another
  2. 3. The state of the matter that has definite volume but not a definite shape
  3. 4. The force holding atoms together to form molecules and compounds, created by the attraction between their electrons and nuclei, allowing them to become more stable by sharing or transferring electrons to fill their outer shells
