the temp of air in a foundry increases when molten metals cool and solidify. Suppose a 45 x 10^6 J of energy is added to the surrounding air by the solidifying metal. The air's temp increases by 55 °C, and the air has a specific heat capacity of 1.0 x 10^3 J/kg x °C. What is the mass of the heated air?
