Air (a diatomic ideal gas) at 26.5°C and atmospheric pressure is drawn into a bicycle pump (see figure below) that has a cylinder with an inner diameter of 2.50 cm and length 63.0 cm. The down stroke adiabatically compresses the air, which reaches a measure pressure of 8.00 105 Pa before entering the tire. We wish to investigate the temperature increase of the pump.
