2. Define temperature

3. The measure of average kinetic energy

4. Absolute zero

5. The temperature at which all matter stops moving -273 o C or 0 K

6. Sublimation

7. The movement of matter from the solid phase to the gaseous phase without going through the liquid phase

8. Solidification or crystalization

9. When matter changes from a liquid to a solid

10. Condensation

11. When matter changes from a gas to a liquid

12. Describe a solid in terms of its shape and volume

13. A solid has a fixed shape and volume this is because the forces between the molecules are very strong MOLECULES ARE VERY CLOSE TOGETHER

14. Describe a liquid in terms of its shape and volume

15. A liquid has an undefined shape (shape of its container) but a fixed volume. This is because the particles are far enough apart to flow but forces between the molecules keep them stuck together

16. Describe a gas in terms of its shape and volume

17. A gas has both and undefined shape and volume (takes the shape and volume of the container) This is because gas molecule are far apart and have little forces between them and can be compressed

18. Going from a solid→liquid→gas is an Process

19. This is an endothermic process because energy must enter to make the molecules move faster and farther apart

20. Going from a gas→liquid→solid is a Process

21. This is an Exothermic process because the molecule are moving slower and “sticking” to each other

30. - 20 0 20 40 60 80 100 120 Heat → Temperature ° C A B C D E What is happening in terms of State of matter, Kinetic energy, and potential Energy) at E

31. It is a gas Kinetic energy is increasing and potential energy is staying the same

32. Freezing point and melting point

33. Freezing point and melting point happen at the same temperature but freezing is going from liquid to a solid and melting is going from a solid to a liquid

34. Evaporation and Vaporization

35. They are both going from a liquid phase to a gaseous phase but vaporization happens at the boiling point and from the molecules within the substance (EX: pot on a stove) and evaporation happens below the boiling point at the surface of the liquid (EX: puddle outside)

36. Kinetic and Potential Energy

37. These are both forms of energy. Kinetic energy is energy in motion while Potential energy is stored energy

38. Endothermic and exothermic

39. Both refer to forms of heat energy. Endothermic energy is entering Exothermic energy is energy that is exiting

40. Heat and temperature

41. Heat is a form of internal energy which can be transferred from one particle to the next. Temperature is a measure of the average kinetic energy of the random motion of its particles.

42. When a substance is changing phases

43. Q = m∆H How much heat energy will it take to melt 10 g of aluminum if its heat of fusion is 94 cal/g

44. When a substance is not changing phases but getting hotter

45. q= m ∆T c p How much heat is needed to warm 25 grams of water from 10 o C to 20 o C? C p = 4.2 J g o C

46. When I have a temperature in o C and I want o F

47. o F = 1.8 o C + 32 Convert 50 o C to o F

48. When I want to go from K to o C

49. K = o C + 273 Therefore o C = K - 273 Convert 298 K to o C

50. When I have a temperature in o F and I want K

51. There is no direct equations first you must use O C = ( O F -32) 1.8 Then K = o C + 273 Convert 68 o F to K

52. What is the name of the device used to measure the heat given off by the burning of a substance?

53. Calorimeter

54. What is the Kinetic theory of matter?

55. All particles of matter are in constant random motion

56. What happens to Kinetic and Potential energy in a cooling curve?

57. They decrease Kinetic energy as substances cool and Potential energy as phase changes occur

58. 1cal = Joules 1 Cal = cal = kcal

59. 1cal = 4.2 Joules 1 Cal = 1000 cal = 1 kcal

60. What units do these come in? Heat (q) Mass (m) Temperature (T) Specific heat (c p ) ΔH=

61. Heat (q) calories or joules Mass (m) grams (g) Temperature (T) o C, o F, K Specific heat (c p ) cal or J g O C g O C ΔH= cal or J gg
