  1. 1. A change of gas into its liquid form.
  2. 3. These are the strongest kinds of forces holding solids together.
  3. 4. This term best describes repeating three-dimensional structure of molecules.
  4. 8. This is a change in form or appearance, but not in chemical composition.
  5. 10. This is a theory that describes how the movement of atoms and molecules affects the properties of matter, such as temperature and pressure.
  6. 18. A change of phase from liquid to solid.
  7. 20. A change in color shows obvious changes that the substance has undergone this certain procedure. The changes are mostly not visible.
  8. 22. This is a process in which it shows that in order for liquid to be converted into gas, temperature must be raised.
  9. 24. This is known as the intermediate phase of Solid and Gas.
  10. 25. The tendency for the same kind of particles to be attracted to one another.
  11. 27. A phase change that converts liquid into gas.
  12. 28. This is very strong and hard to break because their particles are held together very closely.
Down
  1. 1. This is the temperature and pressure above which a substance cannot exist as a liquid, regardless of pressure.
  2. 2. These are held together by metallic bonds, which involves electron sharing throughout the body of the metal. This ranges from soft to hard.
  3. 5. A very thin layer of particles that are more strongly attracted to each other than they are to the particles surrounding them.
  4. 6. This gives trees and other plants a boost in drawing nutrient-rich water from the soil up the stem and into the leaves.
  5. 7. These are made up of electrically-charged particles, hot ionized gas where electrons break free.
  6. 9. A process of changing solid to gas directly without passing through the liquid phase.
  7. 11. These are non-conductors of electricity, but conduct when melted or dissolved into a liquid solution.
  8. 12. A process of changing gas to solid without passing through the liquid phase.
  9. 13. This is a state of matter where atoms cool to near absolute zero, forming a superfluid.
  10. 14. The term is originated from a greek word, meaning shapeless, has a disordered structure at the microscopic level.
  11. 15. This is the property of a liquid to easily vaporize at normal temperatures.
  12. 16. This is a superfluid state of matter formed at extremely low temperatures, similar to a Bose-Einstein Condensate but with different building blocks.
  13. 17. A phase change from solid to liquid through the application of heat.
  14. 19. This phase of matter is known of how particles move very quickly because of the empty space surrounding them.
  15. 21. It is the pressure exerted by the vapor/liquid in a closed container.
  16. 23. This is a measure of how much a liquid resists flowing freely.
  17. 25. This is formed when atoms are combined together.
  18. 26. This is held together by the same kinds of forces that hold liquids together, this is also known as the weakest type and considered to have low melting points, very soft, and non-conductors.
