Question:

Look at Problem 3.183 and plot the P–v diagram for the process. Only T2 is given; how do you determine the second property of the final state? What do you need to check, and does it influence the work term?


Data from Problem 3.183

A piston/cylinder has 0.5 kg of air at 2000 kPa, 1000 K, as shown in Fig. P3.183. The cylinder has stops, so Vmin=0.03m3. The air now cools to 400K by heat transfer to the ambient. Find the final volume and pressure of the air (does it hit the stops?) and the work and heat transfer in the process.
