Air in piston-cylinder assembly undergoes
athermodynamic cycle consisting of three internally
reversibleprocesses in series:
process 1-2: constant volume heating from t1=288k, p1=0.1mpa
top2=0.42mpa
process 2 -3: constant pressure cooling
process 3-1: isothermal heating to the initalstate
employing the ideal gas model with cp=1 kj/kg*k, evaluate
thechange in specific entropy, in kj/kg*k, for each process. sketch
the cycle on p-v and t-s coordinates. for eachprocess, associate
work and heat transfer with areas on thesediagrams,
respectively.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
