1.	One end of a uniform brass rod 20 cm long and 10cm^(2) cross-sectional area is kept at 100^(0)C. The other end is in perfect thermal contact with another rod of identical cross-section and length 10 cm. The free end of this rod is kept in melting ice and when the steady state has been reached, it is found that 360 g of ice melts per hour. The thermal conductivity of the rod, given that the thermal conductivity of brass is 0.25 cal/s cm ""^(0)C and L = 80 cal/g, is 0.111xxK" ca"l//"cm-s-"^(0)C. Then K is equal to
