1.	The two ends of uniform rod of thermal conductivity K are maintained at different but constant temperatre. The temperature gradient at any point on the rod is d theta // dx. The heat flow per unit time per unit cross-section of the rod is I. (i) (d theta)/(dx) is the same for all point on the rod (ii) I = K (d theta)/(dx)
