Curved Surface of a uniform rod is isolated from surrounding. Ends of the rod are maintained at temperatures T1 and T2(T1>T2) for a long time. At an instant, temperature T1 starts to decrease at a constant and slow rate. If thermal capacity of material of the rod is considered, then which of the following statements is/are correct

1.At an instant, rate of heat flow near the hotter end is equal to that near the other end
2.Rate of heat flow through the rod starts to decrease near the hotter end snd remains constant near the other end.
3. Rate of heat flow is maximum at mid section of the rod
4. None of these
