Heat and Thermal ExpansionHard

Question

Three identical rods AB, CD and PQ are joined as shown. P and Q are mid points of AB and CD respectively . Ends A, B, C and D are maintained at 0oC, 100oC, 30oC and 60oC respectively. The direction of heat flow in PQ id : -

Options

A.From P to Q
B.From Q to P
C.Heat does not flow in PQ
D.Data not sufficient

Solution

TP = 50oC; TQ = 45oC
∴ Heat will flow from P to Q
