? The OCHiO of thermal concle- crivities of the two roals are lile. Two rocks are same a- rea and same thermal resi- stance. Then what is the rajio of it's length? ans: A,=A2 -A Rt, = Rt2 l, = 12 K,A K2A
1, = KI f2 K2 l, = 4 1 P2 ?If rate of heat through a conductor is 'q' if the radius of same conductor is doubled and length is halved. Then what is the rate of heat? ans: K, A, l AT Q = KAAT if racious doubled, the area become 4 times A' = 4A Q' = KUAAT l'= 8/2 8/2 K=k = BKADT AT l Q = 8Q
