Two bars are in contact. All sides of the bars are insulated in such a way that heat flow is one-dimensional. Heat flux, temperatures at the end of each bar, and the thermal conductivities of the bars are given as follows. q"=8.2 W/m TA= 48C, XA=0.05, k = 0.1 W/mK TB = 29.8C, xB=0.04, kg = 0.2 W/mK Find the temperature jump in [C] at the contact line.
