34. Compare and contrast thermal energy and temperature when it comes to the size of an object. D 100

35. Since thermal energy is the total energy of the particles in an object, size does matter for TE. The larger the object, the greater the TE. Temperature, being the average energy of the particles, is not influenced by the size of the object. D 100

39. Convection best explains the creation of wind at the beach, as warm air rises and cooler air is pushed down. D 300

40. A thermometer, such as the one above, depends on which method of heat transfer? D 400

41. A thermometer uses conduction. D 400

42. Describe how a refrigerator can cool food down. D 500

43. Thermal energy from the warmer food is transferred to the cooler air in the fridge, causing the food to get cooler, and the air to get warmer. D 500

44. What conversion takes place when natural gas is used to heat a pot of water? E 100
