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