Problem 777

An insulated pistoncylinder device initially contains 300 L of air at 120 kPa and 178C. Air is now heated for 15 min by a 200-W resistance heater placed inside the cylinder. The pressure of air is maintained constant during this process. Determine the entropy change of air, assuming (a) constant specific heats and (b) variable specific heats.
