1.	In case when both the surfaces of plane wall are at different temperature, we get an expression i.e.T MAX T W2 /T W1 TW2 = (B + 1)2/4B
A.	nWhat is the value of B?
B.	(q <sub>g</sub>) ( )<sup>2</sup>/2k (T <sub>W1 </sub> T<sub>W2</sub>)
C.	(q <sub>g</sub>) ( )<sup>3</sup>/3k (T <sub>W1 </sub> T<sub>W2</sub>)
D.	(q <sub>g</sub>) ( )<sup>4</sup>/4k (T <sub>W1 </sub> T<sub>W2</sub>)
E.	(q <sub>g</sub>) ( )<sup>5</sup>/5k (T <sub>W1 </sub> T<sub>W2</sub>)
Answer» B. (q <sub>g</sub>) ( )<sup>2</sup>/2k (T <sub>W1 </sub> T<sub>W2</sub>)
