A slab consists of two parallel layers of iron and brass 10 cm and 10.9 cm thick and of thermal conductivities 500 "Wm"^(-1) "K"^(-1) and 109 "Wm"^(-1) "K"^(-1) respectively. The area of opposite faces are 2m^(2) each and are at temperatures 373 K and 273 K. Find heat conducted per second across the slab and also the temperature of the interface.
