I have this problem: Two (2) kilograms of Nitrogen gas at 600 K and 10 atm are allowed to expand such that they end up occupying three (3) times the initial volume and providing 50% of the isobaric work. mass = 2000 g temp1 = 600 K pressure1 = 1013250 Pa gasC = 8.3144621 n = mass/28.0134 = 71.3944 mol v1 = (n*gasC*temp1)/pressure1 = 0.351506 m^3 v2 = 3*v1 = 1.05452 m^3 w = p1*(v2 - v1) = 712327 J I have to determine v2, temp2, and pressure2 and characterize the process. Where I'm confused is the 50% of isobaric work part. If the system is isobaric wouldn't all of the work being done be a result of the change in volume? Or am I missing something related to a change in temperature that would affect the work being done? Any help would be greatly appreciated.
