4. The particles of this state are close together and vibrate in place

5. What is a solid?

6. The volume and shape of this state can change

7. What is a gas?

8. This state has a definite shape and volume.

9. What is a solid?

10. This is the only state that is compressible.

11. What is a gas?

12. The particles can slide past each other making this state pourable.

a model of a liquid?

17. What is a
model of a gas?

19. What is a model of sublimation?

21. What is a model of ice?

23. What is a model of evaporation?

24. Changes of state are physical changes for this reason.

25. What is because no new substances are formed?

26. Changing from a solid to a liquid is called this.

27. What is “melting”?

28. Changing from a gas to a liquid is called this.

29. What is “condensation”?

30. Carbon dioxide changes from a solid directly to a gas through this process.

31. What is “sublimation”?

32. The freezing point of a substance is the same temperature as this.

33. What is the “melting point”

34. Proven when the mass of ice was the same as the mass of water after melting occurred.

35. What is the Law of Conservation of Mass?

36. Temperature does not change during this process
Temperature does not change during this process. The energy is being used to overcome particular attraction.

37. What is a phase change or a change in state?

38. When energy is absorbed during a phase change.

39. What is an endothermic change?

40. The exception to the rule that matter contracts when cooled.

41. What is water when it freezes?

42. Density, Melting Point, Freezing Point, Condensation Point, Boiling Point.

51. What is condensing?

52. 60 degrees

53. What is the melting point?

54. Type of change represented by the model

55. What is a endothermic?
