Answer 1

When s system is taken from state i to state f along path iaf, ligf = 52 J and Wicf = 24 J. Along path ibf, Qipt = 36 J. AU = 0-W Aviaf = Alibf i-au curred=sliaf 52-34 - 36 - Wibki - Slovenced = -28J soufi -> Wibk= 85 = -15 -28 = -43J 28= 36-Wilf ' Qfi = Whits Ufi 1) Calculate the work done by the system along path ibf.
