1. 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   35   55   Hint Half-n-half Clue   2. The heat gained or lost by a body resulting in a change in temperature is called _______.   latent heat   sensible heat   hidden heat   Half-n-half Clue   3. If 1056 J of heat are gained by 40 g of oil [having a specific heat capacity of 2.4 J/(g oC)], the temperature change in the oil is   11 oC   44 oC    4 oC    96 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 10oC and the heat lost is 160 J, then the mass of the aluminum is   20 g   80 g   16 g   100 g   Half-n-half Clue   5.
