- 3. States that all physical matter exists in the form of particles (atoms or molecules) in constant motion.
- 5. Change of state from a liquid to a solid
- 7. Any change in matter that does not change the composition of the substance
- 8. Describes how a substance changes in the presence of another substance or under certain conditions
- 13. Change of state from a liquid to a vapor (gas)
- 15. Is a pure substance that consists of atoms with the same atomic number.
- 16. State of matter in which the molecules of the substance move wildly about
- 18. Relatively fast form of vaporization that as the substance is heated the particle’s energy creates a pressure equal to the air pressure outside the liquid
- 19. Distinct groups of two or more atoms
- 20. Mass of matter contained within a particular volume
- 22. The mass of a substance will continue to have the same whole numbered ratio.
- 24. Change of state from a solid directly to a gas
- 25. Change of state from solid to liquid
- 27. They have a uniform appearance; also known as a solution
- 29. Change of state from a gas directly to a solid
- 30. A change that alters the composition of the substance
- 31. Relatively slow form a 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
- 32. A material made of only one kind of element or compound; it is not a mixture
- 33. Temperature at which a substance changes from a solid to a liquid
Down
- 1. The building blocks of all matter
- 2. Temperature at which a liquid starts to boil
- 4. Does not have a uniform appearance since the substances are unevenly distributed
- 6. Anything that occupies space and has mass
- 9. A physical combination of two or more substances.
- 10. Amount of matter in an object
- 11. Is a pure substance consisting of atoms of two or more different elements that are chemically combined
- 12. Law that states that matter can not disappear, but changes states
- 13. Space enclosed or occupied by an object
- 14. The measure of gravity acting on the matter of an object.
- 17. State of matter in which the molecules of the substance do not move
- 21. Anything about a substance that can be observed
- 23. State of matter in which the molecules of the substance are between a liquid and a gas
- 26. State of matter in which the molecules of the substance move but the movement is restrained
- 28. Change of state from a gas to a liquid
