Consider a cylinder of a gasoline engine at the beginning of the compression cycle, duringwhich a fuel/air mixture (for our purposes mostly composed of nitrogen and oxygen, i.e.an ideal gas of diatomic molecules) at 300 K and 1 bar is compressed down to one-tenthvolume (compression ratio of 10:1). Assume that the compression is rapid so no heatexchange occurs with the environment. Calculate the pressure and the temperature ofthe compressed gas. In a diesel engine, the compression ratios are typically much higher;redo the same calculation with a compression ratio of 20:1.
