Question

A cylinder with a piston contains 0.250 mol of oxygen at 2.40H10⁵ Pa and 355 K. The oxygen may be treated as anidealgas. The gas first expands isobarically to twice itsoriginalvolume. It is then compressed isothermally to itsoriginal volume,and then it is cooled isochorically to itsoriginal pressure. (a)Show the series of processes on apV – diagram. (b) Computethe temperatureduring the isothermal compression. (c) Compute themaximumpressure. (d) Compute the total work done by the pistononthe gas. (e) Find the absolute value of the total heat flowintoor out of the gas for this sequence of processes, and statethedirection of heat flow.
