There are three slabs placed side by side as shown in figure. Heat generation takes place in slab (2) only and thermal conductivity of slab (1) is greater than that of slab (3). Which one of the following profiles of heat flux is correct. (Consider steady, 1 - D heat conduction and same environmental conditions for both slab (2) and slab (3)).
