(b) You repaired a puncture in your bicycle tyre. To inflate the tyre you use a pump to compress a gas to 0.35 of its initial volume adiabatically during each pumping motion. (i) How many degrees of freedom per particle are exhibited by a diatomic gas such as air, and how many are exhibited by a monoatomic gas such as helium? Assume that any vibrational degrees of freedom may be neglected. (ii) Air with an initial temperature of 6 °C is used for inflation. Calculate the temperature of the air at the end of a pumping motion. (iii) If you instead inflated the tyre using helium with the same compression ratio and initial temperature, what would be the temperature of the helium at the end of a pumping [10 Marks] motion?
