Question

Two rods of length L1 and L2 are made of materials of coefficients of linear

expansions alpha1 and alpha 2

respectively such that L1alpha1=L2alpha2. The temperature of the

rods is increased by ∆T and correspondingly the change in their respective lengths

be ∆L1 and ∆L2

:

A. ∆L1=∆L2

B. ∆L1 not equal to ∆L2

C. The difference in the length (L1-L2) is a constant and is independent of

rise of temperature
