1. If the temperature of 50 g of copper [having a specific heat capacity of 0.4 J/(g oC)] is lowered by 8oC, then the heat lost by the copper is   20 J   3.2 J   400 J   160 J   Hint Half-n-half Clue   2. If 270 J of heat are required to increase the temperature of a body by 30oC, then its heat capacity in J/oC is   3   9   8100   300   Half-n-half Clue   3. 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   4. Sea breezes occur at night.   True   False   5. 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   100 g   80 g   16 g   20 g   Half-n-half Clue   6. Heat capacity = Specific heat capacity x _______.   Weight   Mass   Volume   Half-n-half Clue   7. Given that the specific heat capacity of water is 4.2 J/(g oC), the heat capacity of 90 g of water in J/oC is   360   378   189   756   Half-n-half Clue
