2. The quantity of thermal energy that is transferred.

3. 1 PT heat

4. According to the 2 nd law of thermodynamics, it’s how heat flows

5. 2 PT From the hotter object to the colder object

6. It’s what occurs when heat stops flowing

7. 3 PT Thermal equilibrium (when both objects are the same temperature)

8. It’s the sum of the KE and PE of the particles that compose matter.

9. 4 PT Thermal energy

10. It’s the amount of thermal energy required to raise the temperature of 1kg of a substance by 1 degree C.

11. 5 PT Specific heat capacity

12. According to the kinetic theory, it is why the temperature of a substance increases.

13. 1 PT The particles that make up the substance vibrate faster.

14. It’s the measure of the average kinetic energy of the particles of a substance.

15. 2 PT temperature

16. It’s why the fluid in a thermometer rises.

17. 3 PT The fluid expands as it increases in temperature

18. The quantity of heat either gained or released that causes a phase change from a solid to a liquid or liquid to a solid.

19. 4 PT Latent Heat of Fusion

20. It’s why evaporation cools your skin.

21. 5 PT Heat is absorbed from your sweat when water molecules evaporate, leaving the sweat cooler and your skin cooler.

22. A substance that is able to store a large quantity of heat has this type of specific heat capacity

23. 1 PT High Specific Heat Capacity

24. Its why a bimetallic strip bends in a flame

25. 2 PT One metal expands farther than the other, causing it to bend towards the metal that expands less.

26. The intensity of sunlight decreases as this angle decreases

27. 3 PT The insolation angle

28. Heat engines transfer these two forms of energy, one to the other

29. 4 PT Thermal energy to mechanical energy.

30. What must be absorbed when a substance goes from solid to liquid to gas and from where does it come?

31. 5 PT Thermal energy from the surroundings

32. It’s the three ways that thermal energy is transferred.

33. 1 PT Convection, conduction and radiation

34. This thermal energy transfer process does so by direct contact of two materials with different temperatures.

35. 2 PT Conduction.

36. This thermal energy transfer process occurs when hot, less dense fluids rise and cooler, more dense fluids sink.

37. 3 PT Convection.

38. This thermal energy transfer process occurs by electromagentic waves

39. 4 PT Radiation.

40. It’s what allows hot fluids to rise

41. 5 PT A decrease in density in a substance compared to the surroundings due to expansion

42. These materials transfer heat rapidly.

43. 1 PT Conductors

44. These materials reduce unwanted transfers of thermal energy.

45. 2 PT Insulators

46. It’s the type of heating system that uses air, ductwork and vents

47. 3 PT Forced air heating system

48. It’s the basic 4-step function of any heating system

49. 4 PT Burn a fuel, heat a fluid, circulate the heated fluid, transfer heat

50. This word means the measure of disorder in a system.

51. 5 PT Entropy.
