| Question | Answer |
|---|---|
| 1. matter with no definite volume and no definite shape | gas |
| 2. matter with a definite volume but no definite shape | liquid |
| 3. matter with a definite volume and a definite shape | solid |
| 4. the uneven forces acting on the particles on a liquids surface | surface tension |
| 5. the gas state of a substance that is a solid or liquid at room temperature | vapor |
| 6. a measurement off a liquids resistance to flow | viscosity |
| 7. anything that takes up space and has mass | matter |
| 8. high energy matter consisting of positively and negatively charged particles | plasma |
| 9. the amount of matter in an object | mass |
| 10. the amount of space that a sample of matter occupies | volume |
| 11. mass per unit volume | density |
| 12. ways in which atoms ions or molecules move | particle motion |
| 13. movement in all directions and at different speeds | random motion |
| 14. the way freely moving particles move | straight lines |
| 15. the positively charged parts of atoms | protons |
| 16. the negatively charged parts of atoms | electrons |
| 17. oppositely charged particles attract each other | particle forces |
| 18. the particle speed is slowest and the attractive forces between particles is strongest | solid |
| 19. the particle speed is slower than in a gas and faster than in a solid | liquid |
| 20. the particle speed is the fastest and the attractive forces between particles is the weakest | gas |
| 21. speed of particle movement: solids | slow |
| 22. speed of particle movement: liquids | moderate |
| 23. speed of particle movement: gases | fast |
| 24. strength of forces between particles: solids | strong |
| 25. strength of forces between particles: liquids | moderate |
| 26. strength of forces between particles: gases | weak |
| 27. distance between particles: solids | close together |
| 28. distance between particles: liquids | moderate |
| 29. distance between particles: gases | far apart |
| 30. the particles move randomly in all directions and at different speeds | gas |
| 31. the particles in the matter are close together and vibrate back and forth | solid |
| 32. the distance between the particles is so great there is little or no attraction between them | gas |
| 33. the particles move in straight lines until they collide with something | solid, liquid, and gas |
| 34. the particles are farther apart than in a solid and can move freely and slide past each other | liquid |
| 35. the speed and direction of the particles are changed by collisions | solid, liquid, and gas |
| 36. true or false: opposite charges "repel" each other and create attractive forces between two particles | false; attract |
| 37. true or false: as particles increase speed, attractive forces get "stronger". | false; weaker |
| 38. true or false: as particle force weakens, particle space "increases". | true |
| 39. true or false: the attractive forces in a solid are "strong". | true |
| 40. true or false: strong forces between particles slow particle movement in a liquid with high "surface tension". | false; viscosity |
| 41. true or false: "cohesion" is the attractive force between similar molecules | true |
| 42. true or false: "gas" has the weakest attractive forces between particles | true |
