In Lee's disc experiment two discs are separated by gap of thickness 5 mm. The space between the discs contains a gas of thermal conductivity `3.88 xx 10^(-5) "Wm"^(-1) "K"^(-1)`. At the steady state the temperature, of the two sides of discs are `368K and 333K`. If the area of cross-section the slab is 25 `"cm"^(2)`, calculate the quantity of heat crossing the gas per second.
