Two identical rods AB and CD, each of length L are connected as shown in figure-4.22. Their cross-sectional area is A and their thermal conductivity is k. Ends A, C and D are maintained at temperatures T_(1),T_(2) and T_(3) respectively. Neglecting heat loss to the surroundings, find the temperature at B.

A rod of negligible heat capacity has length 20cm, area of cross section 1.0cm^(2) and thermal conductivity 200Wm^(-1)C^(-1) . The temperature of one end is maintained at 0^(@)C and that of the other end is slowly and linearly varied from 0^(@)C to 60^(@)C in 10 minutes. Assuming no loss of heat through the sides, find the total heat transmitted through the rod in these 10 minutes.

One end of a metal rod of length 1.0 m and area of cross section 100cm^2 is maintained at 100° C. If the other end of the rod is maintained at 0°C, the quantity of heat transmitted through the rod per minute is (Coefficient of thermal conductivity of material of rod =100 W/m-K)

One end of conducting rod is maintained at temperature 50^(@)C and at the other end ice is melting at 0^(@)C . The rate of melting of ice is doubled if:
