  1. 5. Force The weakest force, holding nonmetals together with intermolecular attractions.
  2. 7. Process A phase change that absorbs heat, like melting ice.
  3. 12. A solid’s resistance to scratching, as seen in diamonds.
  4. 14. A gas transforms directly into a solid without passing through the liquid phase.
  5. 15. This state of matter has a definite volume but takes the shape of its container.
  6. 19. Network Bond A strong bond forming solid structures like diamonds and quartz.
  7. 20. Condensate A recently discovered state of matter formed from extreme cold fermions repelling each other.
  8. 22. The process where gas particles lose energy and become liquid.
  9. 25. The ability of metals to be drawn into wires, like copper.
  10. 29. The ability of metals to be hammered into thin sheets without breaking.

  1. 1. Change A reaction where a new substance with different properties is formed.
  2. 2. Solid A type of solid with no definite crystalline structure, like glass.
  3. 3. Highly energetic particles stripped of electrons, commonly found in the Sun.
  4. 4. Solid A solid with a highly ordered repeating pattern of atoms.
  5. 6. Point The temperature where a liquid’s vapor pressure equals external pressure.
  6. 8. Condensate A state of matter occurring at near absolute zero where atoms act as one.
  7. 9. Bond The force responsible for the malleability and conductivity of metals.
  8. 10. A phase change where a solid turns directly into a gas.
  9. 11. Change A transformation that does not alter a substance’s chemical identity.
  10. 13. Process A phase change that releases heat, like freezing water.
  11. 16. The process where particles spread from high to low concentration, like perfume in air.
  12. 17. A measure of a liquid’s resistance to flow, often observed in honey.
  13. 18. Point The specific temperature at which a solid turns into a liquid.
  14. 21. Action The ability of a liquid to flow against gravity in narrow spaces.
  15. 23. A process where liquid molecules escape into the gas phase at the surface.
  16. 24. Tension A liquid property causing water droplets to form spheres.
  17. 26. The state of matter with definite shape and volume.
  18. 27. Bond A force where electrons are transferred between a metal and a nonmetal.
  19. 28. It has neither definite shape nor volume, expanding freely in all directions.
