4. 1. What are the three states of matter

5. Solid Liquid Gas 1. Answer

6. 2. What is the degree for boiling point?

7. 2. 100°C

8. 3.How can I separate iron filings from sand?.

9. Use a magnet

10. 4.If a glass has oil and water in it, where will the water be located and where will the oil be located.

11. The oil will be on the top because the oil has less density than water.

12. 5. What is the degree for melting point?

13. 0°C

14. 6. How are the particles arranged for a solid?

15. The particles are very close together

16. 7. If a thermometer reads 40°C how much more heat energy needs to be added so the thermometer will reach boiling point?

17. Boiling point is 100°C so the amount of heat energy would have to be 60°C

18. 8.Can a mixture be separated? Explain?

19. Yes, a mixture can be separated. Example: salt and pepper can be separated because when you put them together they are still salt and pepper.

20. 9. What is a solution and how can it be separated?

27. Matter is anything that has mass and takes up space

28. 13. Name 3 physical properties of matter

29. Shape, state of matter, texture, smell, density, magnetism, solubility

30. 14. Opposite poles of a magnet _________________, like poles of a magnet _____________________

31. Opposite = attract Like = repel

32. 15. Water can change from one state of matter to another – explain how this happens.

33. Liquid to a solid = freezing Solid to a liquid = melting Liquid to a gas = boiling

34. 16.The particles of a gas are _______________________.

35. Spread far apart and moving very fast

36. 17. Magnetism is the ______________ of repelling and attracting between 2 ____________ of a magnet Force, poles

37. 17. Magnetism is the ______________ of repelling and attracting between 2 ____________ of a magnet

38. 18. Put the following liquids in the right density order in a glass: water, oil, syrup – most dense to least dense

39. Syrup, water, oil

40. 19. Can you separate the “good” candy from the “bad” candy from your Halloween bag? How

41. Yes, using my hand.

42. 20. Describe how to separate rocks from sand
