Figure shows in cros section a wall consisting of four layers with thermal conductivities `K_(1)=0.06W//mK` `K_(3)=0.04W//mK` and `K_(4)=0.10W//mK`. The layer thicknesses are `L_(1)=1.5cm,L_(3)=2.8` cm and `L_(4)=3.5cm` the temperature of interfaces is as shown in figure. energy transfer through the wall is in steady state. Q. The temperature of the inteface between layers 2 and 3 is
