- 3. (d) - mass of matter contained within a particular volume, mass divided by volume
- 6. pure substance consisting of atoms of two or more different elements that are chemically combined
- 7. any change in matter (its appearance) that does not alter its composition
- 10. fast form of vaporization; occur anywhere within the liquid
- 11. (V) - space enclosed or occupied by an object
- 14. close particles,particles vibrate in place, fixed shape and volume, low compressibility, high density, not fluid
- 15. uniform appearance throughout; solution
- 18. anything about a substance you can observe or measure without altering its chemical composition
- 20. a material made of only one kind of element or compound; not a mixture
- 21. slow form of vaporization; only occurs on the surface of the liquid
- 22. change of state from vapor(gas) to liquid; opposite of vaporization
- 25. temperature at which a solid turns to liquid
- 27. building block of all matter; consisting of protons, neutrons, and electrons
- 28. matter can neither be created nor destroyed, but can only change forms
- 29. change of state from a liquid to a vapor (gas)
- 31. ratio of a substances' mass will always be a whole number ratio
- 33. changes that alter the chemical composition of a substance; chemical reaction
- 34. change of state from a solid directly into a vapor without melting first
Down
- 1. change of state from a gas directly into a solid without going into the liquid phase
- 2. no uniform appearance since substances are unevenly distributed
- 4. temperature at which the liquid starts to boil
- 5. (m) - amount of matter in an object
- 8. change of state from a liquid to a solid at its freezing point
- 9. group of two or more atoms covalently bonded together
- 12. change of state from solid to liquid
- 13. all physical matter exists in the form of particles (atoms or molecules) in constant motion
- 16. close particles, particles are able to slide past one another, fixed volume, shape changed to fill container, low compressibility, middle density,fluid, viscosity
- 17. anything that occupies space and has mass
- 19. pure substance that consists of atoms with the same atomic number
- 23. most common in the universe, makes up sun and stars, gas-like, formed at high temperatures, consists of high-energy ions and free electrons
- 24. a physical combination of two or more substances in a changeable ratio; not a pure substance
- 26. how a substance changes in the presence of another substance or under certain conditions
- 30. widely spaced particles, particles are at high speed, volume and shape changes to fill container, high compressibility, low density, fluid, pressure
- 32. measure of gravity acting on the matter of an object
