Heat and Thermal ExpansionHard
Question
The figure shows two thin rods, one made of aluminum [α = 23 × 10-6 (Co)-1] and the other of steel [α = 12 × 10-6(Co)-1]. Each rod has the same length and the same initial temperature. They are attached at one end to two separate immovablewalls. Temperature of both the rods is increased by the same amount, until the gap between the rods vanishes. Where do the rods meet when the gap vanishes?
Options
A.The rods meet exactly at the midpoint.
B.The rods meet to the right of the midpoint .
C.The rods meet to the left of the midpoint.
D.Information insufficient
