1. If 180 J of heat are required to increase the temperature of a body by 20oC, then its heat capacity in J/oC is   3600   2   9   200   Hint Half-n-half Clue   2. Heat capacity = Specific heat capacity x _______.   Mass   Weight   Volume   Half-n-half Clue   3. If 2352 J of heat are gained by 70 g of oil [having a specific heat capacity of 2.4 J/(g oC)], the temperature change in the oil is    7 oC    168 oC   98 oC   14 oC   Half-n-half Clue   4. 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   90 g   72 g   30 g   24 g   Half-n-half Clue   5. Consider the graph of temperature (in oC) vs. time (in minutes) given above showing the cooling curves of liquids A and B. If 10 g of liquid A lose 840 J of heat in the first 6 minutes, the specific heat capacity of liquid A is about _______ J/(g oC).   2.1   14   8.4   21   Half-n-half Clue   6. If the heat capacity of 30 g of aluminum is 24 J/oC, then the specific heat capacity of aluminum in J/(g oC) is   0.8   720   54   1.25   Half-n-half Clue   7. The SI unit of specific heat capacity is _______.   Erg/oC   Joule/oC   Joule/(kg oC)   Half-n-half Clue
