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   21   8.4   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 the decrease in temperature of liquid A in the first 6 minutes is about _______oC.   50   40   55   35   Half-n-half Clue   3. 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   4. If 350 J of heat are required to increase the temperature of a body by 50oC, then its heat capacity in J/oC is   17500   7   400   5   Half-n-half Clue   5. The amount of heat required to raise the temperature of a body by 1oC is called its _______.   latent heat   specific heat capacity   heat capacity   Half-n-half Clue   6. Given that the specific heat capacity of water is 4.2 J/(g oC), the heat capacity of 80 g of water in J/oC is   168   320   336   672   Half-n-half Clue   7. If 2880 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   120 oC   15 oC    8 oC    192 oC   Half-n-half Clue
