An insulated piston-cylinder device initially contains 300 l of air at 120 kpa and 17°c. the
air is now heated for 15 minutes by a 200-w resistance heater placed inside the cylinder.
the pressure of the air is maintained constant during this process. determine the entropy
change of the air assuming (15 points)
a. constant specific heats
b. variable specific heats

Sorry my friend i don't know the answer. i am just in 6th
