Two rods A and B of different materials but same cross section are joined as in figure. The free end of A is maintained at 100°C and the free end of B is maintained at 0°C. If l_2=2l_1,K_1=2K_2 and rods are thermally insulated from sides to prevent heat loses then the temperature theta of the junction of the two rods is

Figure shows an aluminium rod joined to a copper rod. Each of the rods has a length of 20cm and area of ccross section 0.20cm^(2) . The junction is maintained at a constant temperature 40^(@)C and the two ends are maintained at 80^(@)C . Calculate the amount of heat taken out from the cold junction in one minute after the steady state is reached. The conductivities are K_(Al)=200Wm^(-1) ^(@)C^(-1) . and K_(Cu)=400Wm^(-1) ^(@)C^(-1) .

Two rods of material, x and two of y are connected as shown in the figure. All the rods are indentical in length and cross-sectional area. If the end A is maintained at 80^(@)C and the end D is maintained at 10^(@)C , calculate the temperature of the junctions B and C in the steady state. Thermal conductivity of x is double that of y .

Metal rods X and Y of identical cross-sectional area, have lengths 60 cm and 30 cm respectively. They are made of metals of thermal conductivities lambda_(x) and lambda_(y) . They are well-lagged and joined end-to-end as shown in the figure-4.43. One end of X is maintained at 100^(@)C and the opposite end of Y is maintained at 0^(@)C . When steady conditions have been .reached, the temperature of the junction is found to be 25^(@)C . What is the value of (lambda_(x))/(lambda_(y)) ?

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:
