  1. 4. - A substance made up of atoms with the same atomic number
  2. 6. - A substance that is currently gas but normally a liquid or solid at room temperature
  3. 9. Mixture - A mixture made up of particles that are uniformly distributed
  4. 10. Energy - energy that's stays in motion
  5. 11. - Matter with constant composition all particles have the same properties
  6. 12. - Substances that are made from atoms of two or more elements that are chemically bonded
  7. 15. - Very high KE the particles collide with enough energy to break into charged particles
  8. 16. Mixture - A mixture made up of particles that are not uniformly distributed
Down
  1. 1. - Process that releases energy into the surroundings
  2. 2. - Very low KE the particles vibrate but can be moved
  3. 3. - A process that absorbs energy from the surroundings
  4. 5. - Matter with variable composition made from two or more substances
  5. 7. - Low KE the particles can move but are still close
  6. 8. - High KE the particles can separate and move through
  7. 13. - A measure with the amount of matter
