Question: Problem 0 7 . 0 8 8 - Air in an insulated piston - cylinder device An insulated piston cylinder device initially contains 3 4

Problem 07.088- Air in an insulated piston-cylinder device
An insulated pistoncylinder device initially contains 340.0 L of air at 120 kPa and 17C. Air is now heated for 15 min by a 200-W resistance heater placed inside the cylinder. The pressure of air is kept constant during this process.
Problem 07.088.b - Entropy change of air assuming variable specific heats
Determine the entropy change of air assuming VARIABLE specific heats using the entropy term so. Use the table containing the ideal gas properties of air. (Round the final answer to three decimal places.)
The entropy change of air is kJ/K
