An insulated piston-cylinder device initially contains 300 L of air at 120 kPa and 300 K. The air is heated for 15 minutes by a 200 Watt resistance heater inside the cylinder. The air pressure is kept constant during the heating process. Find the entropy change of the air (kJ/oK) using a) the air tables and b) an appropriate constant value of specific heat.
