  1. 2. all particles in matter are identical (fixed composition)
  2. 4. phase of matter where particles of matter are far apart and uniformly distributed throughout the container, take the shape and volume of the container. Has the most energy of the three common phases
  3. 5. The study of the composition, structure, and properties of matter, the processes that matter undergoes, and the energy changes that accompany these properties.
  4. 8. phase change when a solid changes directly to a gas
  5. 9. anything that takes up space and has mass
  6. 12. two or more atoms chemically bonded
  7. 13. two or more elements chemically combined in a fixed proportion
  8. 14. phase change when a liquid changes to a solid
  9. 16. Mixture components are evenly distributed out on a microscopic level
  10. 19. phase change when a gas changes directly to a liquid
  11. 20. phase change when a liquid changes to a gas
Down
  1. 1. phase change when a gas changes to a liquid
  2. 3. two or more substances physically combined (variable composition)
  3. 6. Mixture substances in the mixture are not evenly spread out
  4. 7. phase of matter where particles of matter are loosely packed and are free to move past one another, take the shape of their container, but cannot be compressed. They have a medium amount of energy
  5. 10. the smallest unit of matter (particle of an element) that retains the chemical properties of the element
  6. 11. phase of matter where particles of matter are tightly packed together, have a definite fixed shape, cannot be compressed and have the least amount of energy
  7. 15. a pure substance that cannot be broken down into simpler substances by physical and chemical means
  8. 17. phase change when a solid changes to a liquid
  9. 18. phase of matter where matter becomes ionized as electrons are broken loose from the atoms
