A rod of length l and of a uniform cross-sectional area A is made of a material of non-uniform thermal conductivity. Its thermal conductivity is temperature depenndent and varies as K=(B)/(T), where B is a constant. If ends of the rod are maintained at constant temperatures T_(1) and T_(2) with T_(1)gt T_(2), rate of flow of heat in steady state will be :

1.	A rod of length l and of a uniform cross-sectional area A is made of a material of non-uniform thermal conductivity. Its thermal conductivity is temperature depenndent and varies as K=(B)/(T), where B is a constant. If ends of the rod are maintained at constant temperatures T_(1) and T_(2) with T_(1)gt T_(2), rate of flow of heat in steady state will be :
