1. Explain how much heat in J is added to a 6.78 g iron nail to raise its temperature from 22oC to 469.9oC where the specific heat of iron is 0.45 J/ (goC).
2. Explain how long would it take in seconds to increase the temperature of the water from 12.0oC to41.5oC when a bowl of 345 g of water is placed in a microwave oven that puts out the 766 watts (J/s).
3. Calculate the heat capacity of a calorimeter in J/oC if the 360.8 J of heat raises its temperature by 4.4oC?
