How much heat is required to convert 12.0 g of ice at -10C to steam at * 2 points 100C? ( cice= 0.5 cal/g C"; Lf= 79.7 cal/g; cwater= 1 cal/g 0; Lv= 539 cal/g) 0 864.84 cal O 0.08 cal 0 8684.4 cal O 8.64 cal An inventor suggests that a house might be heated by using a refrigerator * 1 point to draw energy as heat from the ground and reject energy as heat into the house. He claims that the energy supplied to the house as heat can exceed the work required to run the refrigerator. This: 0 is impossible by rst law 0 is impossible by second law 0 would only work if both were at the same temperature 0 is possible In a thermally insulated kitchen, an ordinary refrigerator is turned on and its * 1 point door is left open. The temperature of the room 0 remains constant according to the rst law of thermodynamics 0 increases according to the rst law of thermodynamics 0 decreases according to the rst law of thermodynamics 0 remains constant according to the second law of thermodynamics
