One end of a copper rod of length 1.0 m and area of cross section (10^-3) m^2 is immersed in boiling water and the other end in ice. If the coeeficient of thermal conductivity of copper 92 cal/ms/(degree celsius) and the latent heat of ice is 8*10^4 cal/kg then the amount of ice that will melt is: a) 9.2*10^-3 kg b)8*10^-3 kg c)6.9*10^-3 kg d)5.4*10^-3 kg
