  2. 5. mixture- A mixture that has a uniform appearance throughout
  3. 7. The measure of the amount of matter in an object.
  4. 10. mixture- A mixture that does not have a uniform appearance throughout
  5. 12. of conversation of matter- A model, often expressed as a mathematical equation, that describes phenomena under certain conditons.
  6. 14. change- Any change in matter that does not alter its chemical or nuclear composition
  7. 18. A pure substance consisting of atoms of two or more elements that are chemically combined in a fixed ratio.
  8. 20. A particle consisting of two or more atoms covalently bonded together.
  9. 22. The change of state from a solid to a liquid.
  10. 23. substance- A material made of only one kind of element or compound
  11. 24. The relatively fast form of vaporization in which the energy within a liquid creates higher pressure within the liquid than the air pressure outside the liquid
  12. 26. property- Anything about a substance that can be observed or measured without altering its chemical composition

  14. 31. Anything that has mass and occupies space.
Down
  1. 1. The relatively slow form of vaporization in which liquid particles obtain sufficient energy to change to the gaseous state through the random collisions of particles.
  2. 3. The change of state from gas (vapor) to a liquid.
  3. 4. The space enclosed or occupied by an object
  4. 6. model of matter- A model that states that all physical matter exists in the form of particles.
  5. 8. The force of gravity acting on the matter in an object

  7. 11. A pure substance that consists of atoms of the same atomic number.
  8. 13. the building block of all matter
  9. 15. The state of matter in which particles vibrate in fixed positions, giving a substance a fixed shape and volume
  10. 16. The mass per unit volume of an object
  11. 17. The change of state from a liquid to a solid.
  12. 19. The change in state directly from a gas (vapor) to a solid without condensing first.
  13. 21. point- The temperature at which a solid turns to a liquid
  14. 25. A physical combination of two or more substances in a changeable ratio
  15. 27. The state of matter in which particles are close together but able to move around
  16. 28. of definite proportions- The law that states that the masses of chemical substances combine in definite, characteristic integer ratios when forming compounds
  17. 29. change- A change that alters the chemical composition of a substance
