1. Calculate the work done in compressing isothermally 2kg of dry air to one-tenth its volume at 15C



2. Work= the integral of pressure times the change in volume, the limits of integration being the initial and final volumes, v1 and v2.



3. The equation is very general, and doesn't have a variable for mass of the air parcel. The problem also doesn't have a value for p, so I dunno if I am supposed to have a solution with p as a variable in it...

Just set up the integral leaving variables where you don't know something. You may find the answer doesn't depend on things you don't know.
