  2. 3. the state of matter in which the volume and shape of a substance are fixed
  3. 6. a measure of the amount of matter in an object
  4. 8. a substance that cannot be separated or broken down into simpler substances by chemical means
  5. 10. a measure of how hot (or cold) something is; specifically, a measure of the average kinetic energy of the particles in an object
  6. 15. a strong force that holds atoms together
  7. 16. the amount of force exerted per unit area of a surface

  2. 4. The amount of space something takes up
  3. 5. the amount of space that an object takes up, or occupies
  4. 6. anything that has mass and takes up space
