A metal rod of cross sectional area 1.0 cm2 is being heated at one end. At one time, the temperature gradient is 5.0∘Ccm−1 at cross section A and is 2.5∘Ccm−1 at cross section B. Calculate the rate at which the emperature is increasing in the part AB of the rod. The heat capacity of the part AB=0.40J∘C−1, thermal conductivity of the material of the rod = 200Wm−1∘C−1. Neglect any loss of heat to the atmosphere. |
