Unit 2 Review

4. by a temperature change, it occurs throughout the liquid.
5. or more elements chemically combined.
9. particles in matter are identical (fixed composition).
11. that shows the state of matter transitions and all of the heat and energy that is added to it.
12. phase and state transition from liquid to gas.
15. in a substance that affects its chemical properties and a chemical reaction occurs.
17. the atomic symbol “Au” on the periodic table.
18. of matter where there is a fixed volume, but the shape changes based on its container.
19. of mixture where components are evenly distributed.
20. of matter where there is a fixed volume and shape.
21. by pressure change, occurs at the surface of a liquid.
22. of the average kinetic energy of the particles in an object.
23. that can only be measured or observed by changing the chemical identity.
24. composed of positively and negatively charged particles with high kinetic energy. Most of the universe is made of this.

1. by which the atoms of one or more substances are rearranged.
2. of mixture where components are unevenly distributed.
3. that can be observed directly or measured without changing the chemical identity of the substance.
6. or more substances physically combined (variable composition).
7. of matter where there is no fixed volume or shape.
8. in a substance that only affects its physical properties.
10. form of matter.
13. the atomic symbol “C” on the periodic table.
14. sum of the kinetic and potential energy of particles in an object.
16. that takes up space and has mass.
20. the atomic symbol “Ag” on the periodic table.
