A uniform rod with an insulated curved surface has its ends held at and () for a long time. Then the temperature of the hot reservoir starts to fall slowly. If the heat capacity of the rod is taken into account, which of the following statements is/are correct, just after this instant?
Options:(select one or more)
Answer:
B
Solution:
With falling, the temperature profile flattens and the stored energy of the rod decreases. The rod therefore releases heat, so (heat out at the cold end) \> (heat in at the hot end). A and C need steady state, and D has the sign reversed. Option B.
