A storage room is 4 m wide by 7 m long by 3.2 m high. Its temperature is 18 °C. The barometer is steady at the average Edmonton value. Consider the air to be an ideal gas. Determine the specific heat of air at constant pressure, and at constant volume. a. How much heat is required to raise the temperature of the air to 28 °C, assuming that the room is open to the atmosphere (pressure is constant)? b. How much heat is required to raise the temperature of the air to 28 °C, assuming that the room is completely sealed (keeping the volume constant)? c.
