Question:

A handheld pump for a bicycle has a volume of 25 cm3 when fully extended. You now press the plunger (piston) in while holding your thumb over the exit hole so that an air pressure of 300 kPa is obtained. The outside atmosphere is at P0, T0. Consider two cases: (1) it is done quickly (∼1 s), and (2) it is done very slowly (∼1 h).
a. State assumptions about the process for each case.
b. Find the final volume and temperature for both cases.
