An air pump has a cylinder 0.220 mm long with amovable piston. The pump is used to compress air from theatmosphere (at absolutepressure 1.01×105Pa into a very large tankat 3.60×105 Pa gauge pressure. (For air,CV = 20.8 J/mol⋅KJ/mol⋅K.)
a)
The piston begins the compression stroke at the open end of thecylinder. How far down the length of the cylinder has the pistonmoved when air first begins to flow from the cylinder into thetank? Assume that the compression is adiabatic.
b)
If the air is taken into the pumpat 25.0 ∘C, what is the temperature of thecompressed air?
c)
How much work does the pump do in putting 25.0 mol of airinto the tank?
