Across
  1. 2. of mixture where components are unevenly distributed.
  2. 3. the atomic symbol “Au” on the periodic table.
  3. 7. the atomic symbol “Ag” on the periodic table.
  4. 13. phase and state transition from liquid to gas.
  5. 14. the atomic symbol “C” on the periodic table.
  6. 15. of matter where there is no fixed volume or shape.
  7. 17. energy/The sum of the kinetic and potential energy of particles in an object.
  8. 18. properties/Properties that can only be measured or observed by changing the chemical identity.
  9. 21. of mixture where components are evenly distributed.
  10. 22. by pressure change, occurs at the surface of a liquid.
  11. 23. composed of positively and negatively charged particles with high kinetic energy. Most of the universe is made of this.
  12. 25. by a temperature change, it occurs throughout the liquid.
Down
  1. 1. reaction/Process by which the atoms of one or more substances are rearranged.
  2. 4. particles in matter are identical (fixed composition).
  3. 5. or more substances physically combined (variable composition).
  4. 6. form of matter.
  5. 8. of matter where there is a fixed volume, but the shape changes based on its container.
  6. 9. properties/Properties that can be observed directly or measured without changing the chemical identity of the substance.
  7. 10. of the average kinetic energy of the particles in an object.
  8. 11. or more elements chemically combined.
  9. 12. change/Change in a substance that only affects its physical properties.
  10. 16. of matter where there is a fixed volume and shape.
  11. 19. that takes up space and has mass.
  12. 20. change/Change in a substance that affects its chemical properties and a chemical reaction occurs.
  13. 24. curve/Diagram that shows the state of matter transitions and all of the heat and energy that is added to it.
