5. The temperature of air in a foundry increases when molten metals cool and solidify. Suppose 9.9 X 10 J of energy is added to the sur- rounding air by the solidifying metal. The air's temperature increases by 55 K, and the air has a specific heat capacity of 1.0 x 100 J/kg. K. a. What is the mass of the heated air? b. Assuming a density of 1.29 kg/m', what is the heated air's volume?
