Air (a diatomic ideal gas) at 26.5C 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 55.0 cm. The downstroke adiabatically compresses the air, which reaches a gauge pressure of 8.00 x 10 Pa before entering the tire. We wish to investigate the temperature increase of the pump. A boy inflates his bicycle tire with a hand-operated pump. Kinetic theory helps to describe the details of the air in the pump. ( Cengage (a) What is the initial volume of the air in the pump? 0.0245 x Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully, m (b) What is the number of moles of air in the pump? 1 x Your response differs significantly from the correct answer.

Assume 4.00 cm of the cylinder's length is allowed to come to thermal equilibrium with the air. (9) What is the volume of steel in this 4.00-cm length? x Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. m (h) What is the mass of steel in this 4.00-cm length? (The density of steel is 7.56 x 10 kg/m.) x Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. 9. (1) Assume the pump is compressed once. After the adiabatic expansion, conduction results in the energy increase in part (1) being shared between the gas and the 4.00-cm length of steal. What will be the increase in temperature of the steal after one compression? (The specific heat of steel is 448 J/kg. C.) x Your response differs from the correct answer by more than 10%.
