1. 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   Hint Half-n-half Clue   2. Sea breezes occur at night.   True   False   3. The amount of heat required to raise the temperature of a unit _______ of a material by 1oC is called its specific heat capacity.   volume   weight   mass   Half-n-half Clue   4. Which of the following substances has the highest specific heat capacity ?   Aluminum   Iron   Water   Copper   Half-n-half Clue   5. If 1680 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   70 oC    168 oC   10 oC    7 oC   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 5oC and the heat lost is 120 J, then the mass of the aluminum is   40 g   50 g   24 g   30 g   Half-n-half Clue   7. 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 A   liquid B
