Thermodynamics help required?

Air at 60 degrees C is initially contained in an insulated piston-cylinder container with a volume of 0.4m^3 at 4 bar pressure. It proceeds to undergo a sequential series of thermodynamic changes.

Process 1: constant pressure heating until the temperature reaches 150 degree's C

Process 2: Constant volume cooling until the pressure reduces to 3 bar, and

Process 3: Polytropic compression, where PV^1.5 = constant, until the volume becomes 0.1m^3

Assuming that the characteristic gas constant of air is R = 290 j/kgK

determine the temperature of air after process 2.

Best answer will be awarded. Thanks.
