  8. 13. a state of matter that has a definite shape and a definite volume
  9. 16. An attractive force between two different molecules caused by charge imbalances within the molecules
  10. 17. the phase change that occurs when a solid goes to a liquid
  11. 18. a state of matter that has a definite volume but no definite shape
  12. 20. Point the pressure and temperature at which all three phases of matter exist all at once
