Across
  1. 1. this is a very thin layer of particles that are strongly attracted to eachother than they are o the particles surrounding them what is it?
  2. 7. this changes from solid to liquid with heat what is it?
  3. 9. these are also atoms that merge at super low temperatures to form a single object that behaves like a wave.
  4. 12. this changes from gas to liquid form.
  5. 15. this is the process of changing solid to gas passing the liquid phase
  6. 17. this is the pressure required to liquefy a gas.
  7. 18. what happens when a change in color shows obvious chemical changes that the substance has undergone?
  8. 19. __ will occur when the vapor pressure of liquid is equal to or greater than the atmospheric pressure what is it?
  9. 24. this is a state of matter of a dilute gas of bosons cooled to temperatures close to absolute zero, or the lower limit of the thermodynamic scale.
  10. 25. this force is the weakest among the type of solids held together what is it?
  11. 26. this theory has 5 assumptions, what is it?
  12. 28. this type of solid has high melting points, what is it?
  13. 29. this is the process by which water is converted to its gaseous form from its liquid form.
  14. 30. this type of phase of matter is very strong and hard to break what is it?
Down
  1. 2. these are the strongest kinds of forces holding solids together what is it?
  2. 3. these are the greatest beneath the surface of the liquid, where the particles are attracted to each other on all sides. what are these?
  3. 4. these gives trees and other plants a boost in nutrient-rich water what are these?
  4. 5. this accounts for the capillary action when a liquid is drawn up into a very narrow tube, what is it?
  5. 6. what is the greek meaning of the word "amorphous?"
  6. 8. this is a measure of how much a liquid resists flowing freely.
  7. 10. what involves changing the physical properties of a substance?
  8. 11. the process of changing solid to gas w/o passing the liquid phase
  9. 13. this converts liquid to gas what is it?
  10. 14. a type of gas we encounter this everyday without realizing it at all what is it?
  11. 16. what are metallic solids held together by?
  12. 20. this is the property of liquids that can easily vaporize at normal temperatures
  13. 21. this is the pressure exerted by the vapor/liquid in a closed container.
  14. 22. solids, when exposed to x-rays each structure also produces a distinctive pattern that can be used to identify the material what is it?
  15. 23. since the particles of this phase of matter are very far apart they do not have a definite shape or volume what is it?
  16. 27. this state of matter is an intermediate phase between solid and gas, what is it?
