The temperature of air in a foundry increases when molten metals cool and solidify. Suppose 9,900,000 J of energy is added to the surrounding air by the solidifying metal. The air’s temperature increases by 5 C, and the air has a specific heat capacity of 1,000 J/g*C. What is the mass of the heated air?
