Down
- 1. Change of state from a liquid to a solid
- 2. State of matter in which the molecules of the substance are between a liquid and a gas
- 3. States that all physical matter exists in the form of particles (atoms or molecules) in constant motion
- 4. The mass of a substance will continue to have the same whole numbered ratio
- 5. Distinct groups of two or more atoms
- 8. Does not have a uniform appearance since the substances are unevenly distributed
- 12. A relatively slow form of vaporization in which particles on the surface of the liquid state obtain sufficient energy to change to the gaseous state through the random collisions with particles
- 13. A pure substance consisting of atoms or ftwo or more different elements that are chemically combinied
- 16. A material made of only one kind of element or compound; it is not a mixture
- 19. Change of state from a gas directly to a solid
- 22. They have a uniform appearance; also known as a solution

- 31. Change of state from a solid directly to a gas
- 32. State of matter in which the molecules of the substance move but the movement is free but restricted
