Let the rise in temperature be
The expansion in length due to change in temperature is given by the expression lαΔt , where l is the length, α is the coefficient of linear expansion, Δt is the change in temperature.
Here l = 93 m, α =
, and Δt =
So expansion in length = 93**5 = 0.007905 m =
So order of magnitude in change in length = -3
