Problem D2:
You have two rods made of different metals. When both rods are placed in ice water
(0 Deg C) they have the same length, L_{0}. However, when both rods are placed in boiling
water (100 Deg C) one of the rods expands more than the other. What is the difference in
their lengths, L_{2} - L_{1}, in the boiling water? If L_{2} -
L_{1} = L_{0}/n_{3}, what is n_{3}? The coefficient
of linear expansion for rod 1 is &alpha_{1}=1/n_{1} C^{-1}. The
coefficient of linear expansion for rod 2 is &alpha_{2}=1/n_{2} C^{-1}.
Note that n_{3} is unitless and is negative if L_{1} > L_{2}.
