1. If 83680 J of heat are required to raise the temperature of 4 kg of water by 5oC, then the specific heat capacity of water in J/(kg oC) is   20920   16736   8368   4184   Hint Half-n-half Clue   2. During the day, the sea gets heated more quickly than the land because the specific heat capacity of the land is less than that of the sea.   True   False   3. If 560 J of heat are required to increase the temperature of a body by 40oC, then its heat capacity in J/oC is   4   22400   14   600   Half-n-half Clue   4. If 2688 J of heat are gained by 80 g of oil [having a specific heat capacity of 2.4 J/(g oC)], the temperature change in the oil is    192 oC   112 oC   14 oC    8 oC   Half-n-half Clue   5. If the heat capacity of 25 g of aluminum is 20 J/oC, then the specific heat capacity of aluminum in J/(g oC) is   500   0.8   45   1.25   Half-n-half Clue   6. If the temperature of a certain mass of aluminum [having a specific heat capacity of 0.8 J/(g oC)] is lowered by 9oC and the heat lost is 216 J, then the mass of the aluminum is   24 g   72 g   30 g   90 g   Half-n-half Clue   7. The amount of sensible heat gained or lost by a body is the product of its heat capacity and the _______ change.   time   heat   temperature   Half-n-half Clue
