1. The problem statement, all variables and given/known data A gas is trapped in a cylinder-piston arrangement. The initial pressure and volume are 13,789.5 Pa and 0.02832 m^3. Determine the work(kj) assuming that the volume is increased to 0.08496 m^3 in a polytropic process with n=1. 2. Relevant equations m_1-2=∫PdV from 1 to 2 3. The attempt at a solution I believe the equation for n=1 i would use is P1*V1*ln(V2/V1), however i have to show how i would get that from the intial integral, and i am completely lost as to how i can get there. Also if this is not the correct forum for this post i am sorry, please let me know and i will re-post it in the correct location.
