A piston (with an area of 3.14 x 10^-2 m/s^2) is pushing down on a vertical cylinder (with a pressure of 1.01 x 10^5 Pa) which contains an monotomic ideal gas. 2093 J of heat is removed from the gas.

Ignoring the mass of the piston or friction, find how far the piston has dropped.

2. Relevant equations

I believe that I will have to use Uf-Ui = Q - w,

but I have already figured that the process would have to be isobaric, whoch is goverend by the equation W = P (Vf-Vi), which can be suited to our needs by using distance multiplied by area for the volume, so

W = P A(change in d)

Im wondering if I am going to have to use formulas related to specific heat capacities, but Im not quite sure. Any ideas?
