Problem
The barrel of a frictionless syringe contains a sample of gas that can expand freely so that the pressure on the gas remains equal to the external atmospheric pressure.
Initially the gas occupies 60cm3 at 27∘C. The temperature is first lowered to 0∘C and then raised to 100∘C, all changes taking place at constant pressure.
(i) Determine the volume of the gas after the cooling to 0∘C.
(ii) Determine the volume after the subsequent heating to 100∘C.
(iii) Calculate the ratio of the final volume to the initial volume.
