Answer:
When the heated bar is left unlagged with temperatures T1 and T2 at extreme ends ( T1 > T2 ), temperature at each point of the rod
will decrease due to radiation. Radiative heat loss at a point is proportional to difference between the temperature at that point
and environment temperature. Since temperature T1 is greater than T2 , the end where the initial temperature is T1 will suffer more
radiation loss of heat energy compare to the other end where the temperature is T2 .
Hence the graph shown in blue colour will represent the variation of temperature with respect to distance
