A sample consisting of 1.45 mol of perfect gas atoms is taken through the following cycle: step1 constant pressure, change in volume from 22.44L to 44.88L. Step2 Constant volume, change pressure from 1bar to .35bar. step3 pressure and volume change back to 1 bar and 22.44L. how do i calculate temperature,q,w,deltaU,deltaH,deltaS, and deltaA for each step of the cycle and the overall cycle?
