Across
  1. 7. molecule that shares electrons equally and does not have oppositely charged ends
  2. 8. attractions between oppositely charged regions (+ and -) of polar molecules
  3. 9. the phase change that occurs when a solid goes directly to a gas
  4. 13. molecule with an unequal distribution of charge, resulting in the molecule having a positive end and a negative end
  5. 16. the phase change that occurs when a solid goes to a liquid
  6. 17. a diagram that shows the pressures and temperatures at which the three phases of matter are found
  7. 20. strong type of intermolecular dipole-dipole attraction. Occurs between hydrogen and F, O or N
  8. 21. the phase change that occurs when a liquid goes to a solid
  9. 23. the pressure and temperature at which all three phases of matter exist all at once
Down
  1. 1. An attractive force between two different molecules caused by charge imbalances within the molecules
  2. 2. the phase change that occurs when a gas goes directly to a solid
  3. 3. the intermolecular attractions resulting from the constant motion of electrons and the creation of very short lived imbalances of charge
  4. 4. the phase change that occurs when a gas goes to a liquid
  5. 5. a measurement of the average kinetic energy in a piece of matter
  6. 6. the energy of motion
  7. 10. an instrument that measures atmospheric pressure
  8. 11. a state of matter that has a definite shape and a definite volume
  9. 12. a state of matter that has no definite shape and no definite volume
  10. 14. a state of matter that has a definite volume but no definite shape
  11. 15. the phase change that occurs when a liquid goes to a gas
  12. 18. force applied per unit area; caused by the collision of gas particles with each other and the sides of the container
  13. 19. the energy of position
  14. 22. the pressure and temperature at which a supercritical fluid is formed; cannot distinguish between a gas and a liquid
