Across
  1. 6. A change that alters the chemical composition of a substance
  2. 9. point The temperature at which a solid turns into a liquid
  3. 11. the change from solid directly to a gas
  4. 12. , Their particles move very quickly because of the empty space surrounding them
  5. 13. the change from liquid to gas
  6. 17. A change where you bend a metal spoon
  7. 19. Attraction between the particles of a liquid to the particles that make up the container. Plasma, Often called the fourth state of matter, this state consists of electrically-charged particles
  8. 21. The attractive force between the same kind of particles Surface tension, The property of a liquid's surface that resists external forces
  9. 23. Formed from the electrostatic attraction between oppositely charged ions
  10. 24. how thick or thin a liquid is and a measure of how much a liquid resists flowing freely Capillary Action, The movement of a liquid up a narrow tube or space, due to the combined forces of adhesion and cohesion
  11. 25. phase change from solid directly to gas
Down
  1. 1. The pressure exerted by the vapor/liquid in a closed container
  2. 2. A property describing how easily a substance can be hammered into a sheet
  3. 3. the change from gas to liquid
  4. 4. Property that easily vaporize at normal temperatures
  5. 5. Condensate, Naturally repel from each other because they have an odd number of electrons, protons, and neutrons
  6. 7. the change from liquid to solid
  7. 8. This solid consists of molecules held together by relatively weak intermolecular forces Covalent Network Solid, Known for its extreme hardness and high melting point due to strong bonds extending throughout its structure
  8. 10. state of matter that's formed at extremely low temperatures close to absolute zero
  9. 14. Lacks a well-defined crystal structure with its disordered atomic arrangement
  10. 15. They are good conductors of heat and electricity
  11. 16. Takes the shape of its container but has a definite volume
  12. 18. , A substance with a definite shape and volume, particles closely packed:
  13. 20. the change from solid to liquid Crystalline Solid, This solid is characterized by a highly ordered repeating three-dimensional arrangement of atoms
  14. 22. point The temperature at which a liquid turns into a gas
