Asystem executes a power cycle while receiving 1050 kj by heat transfer at a tempreture of 525 k and discharging 700 kj by heat tranfer at 350 k. there are no other heat transfers.
a) usin equation 5.13 determine whether the cycle is internally reversible, irreversible, or impossible
b) determine the thermal efficiency using equation 5.4 and the given heat transfer data. compare this calue with the carnot efficiency calculated using equation 5.9 and comment

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.
