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   4184   16736   20920   8368   Hint Half-n-half Clue   2. Consider the graph of temperature (in oC) vs. time (in minutes) given above. From the cooling curves, it is observed that _______ cools more rapidly.   liquid B   liquid A   3. Heat capacity = Specific heat capacity x _______.   Mass   Weight   Volume   Half-n-half Clue   4. 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   5. If 1680 J of heat are gained by 50 g of oil [having a specific heat capacity of 2.4 J/(g oC)], the temperature change in the oil is    120 oC    5 oC   70 oC   14 oC   Half-n-half Clue   6. Given that the specific heat capacity of water is 4.2 J/(g oC), the heat capacity of 50 g of water in J/oC is   200   210   420   105   Half-n-half Clue   7. The SI unit of specific heat capacity is _______.   Erg/oC   Joule/oC   Joule/(kg oC)   Half-n-half Clue
