Down
  1. 1. A transition between different states of matter, such as from solid to liquid or liquid to gas
  2. 2. a heterogeneous mixture in which particles are dispersed in a liquid or gas but will eventually settle out
  3. 3. a method to separate solids from liquids or gases using a porous barrier
  4. 4. a state of matter that has a definite shape and volume, with particles closely packed
  5. 5. the process by which a gas changes into a liquid
  6. 7. the phase change in which a solid turns directly into a gas without passing through the liquid phase

  9. 11. A characteristic of a substance that describes its ability to undergo a chemical change
  10. 13. A mixture in which the components are uniformly distributed and cannot be distinguished, such as air or saltwater
  11. 14. the ability of a substance to burn or ignite in the presence of oxygen
  12. 15. A process that produces one or more new substances with different properties
  13. 17. the amount of heat energy required to change a liquid into a gas at its boiling point
  14. 21. a reaction or process that absorbs heat from the surroundings
  15. 23. A characteristic of a substance that can be observed or measured without changing its chemical identity, such as color or density
  16. 25. A mixture in which the components are not uniformly distributed and can often be seen with the naked eye, such as a salad
  17. 26. a measure of a fluid's resistance to flow, often described as its thickness or stickiness
  18. 28. the process by which a liquid changes to a gas at temperatures below the boiling point
  19. 31. a state of matter that has a definite volume but no definite shape, taking the shape of its container
