Across
  1. 2. A type of solid where the atoms are arranged randomly and lack a definite structure, like glass or plastic
  2. 8. The process of changing from a liquid to a gas, like water turning into steam
  3. 10. The process of changing from a solid to a liquid, like ice turning into water
  4. 13. The state of matter that takes the shape of its container but has a fixed volume, like water
  5. 14. The process of changing from a liquid to a solid, like water turning into ice
  6. 15. The state of matter that fills any container it's in and can be invisible, like air
  7. 16. A type of solid where the molecules are held together by intermolecular forces, like ice or sugar
  8. 17. A type of solid formed by the electrostatic attraction between ions, like table salt or sodium chloride
  9. 19. A type of fluid that has a constant viscosity regardless of the applied stress, like water or oil
  10. 20. A type of fluid whose viscosity changes when stress or a force is applied, like ketchup or slime
  11. 21. The process of changing from a gas to plasma by adding energy
  12. 22. A type of solid where atoms are connected by covalent bonds in a continuous network, like diamond or quartz
Down
  1. 1. The process of changing directly from a gas to a solid without becoming liquid, like frost forming on a cold surface
  2. 3. A type of solid that has free electrons and conducts electricity, like iron or copper
  3. 4. A type of solid where the atoms are arranged in a repeating, orderly pattern, like diamonds or table salt
  4. 5. The process of changing from plasma back to a gas by removing energy
  5. 6. The state of matter with a fixed shape and volume, like ice or a rock
  6. 7. The process of changing directly from a solid to a gas without becoming liquid, like dry ice
  7. 9. A phase of matter that flows without viscosity, meaning it can flow without losing energy, like liquid helium at very low temperatures
  8. 11. The state of matter found in stars and lightning, with electrically charged particles
  9. 12. A phase of matter that combines properties of solids and superfluids, where atoms are arranged in a solid structure but can flow without friction
  10. 18. The process of changing from a gas to a liquid, like steam turning into water
