An air pump has a cylinder 0.220 mm long with amovable piston. The pump is used to compress air from theatmosphere (at absolute pressure 1.01×105 Painto a very large tank at 3.80×105 Pa gaugepressure. (For air, CV = 20.8 J/mol⋅K.)
a)The piston begins the compression stroke at the open end ofthe cylinder. How far down the length of the cylinder has thepiston moved when air first begins to flow from the cylinder intothe tank? Assume that the compression is adiabatic.
b)If the air is taken into the pump at 28.0°C, what isthe temperature of the compressed air?
c)How much work does the pump do in putting 20.0 mol of air intothe tank?
