Problem

Temperature difference of

120^{\circ}\text{C}

is maintained between the two ends of a uniform rod

AB

of length

2L

. Another bent rod

PQ

, of same cross-section as

AB

and length

\frac{3L}{2}

, is connected across

AB

(see figure). In steady state, temperature difference between

P

and

Q

will be close to ![Diagram showing a uniform rod AB of length 2L. A bent rod PQ, of length 3L/2, is connected across AB. The rod PQ consists of a horizontal segment of length L and a vertical segment of length L/4. The connection points are A and B on the main rod, and P and Q on the bent rod. The horizontal segment PQ is of length L, and the vertical segment is of length L/4.](https://storage.googleapis.com/diraq-contents/homework-question-parsing/marker/20260106T182719Z/ef255a57a93d423ea8a0136af7043dd5/935eed7aa61f7777f62cfc032e11bee9_img.jpg) (a)
