An aluminum bat is 17 m long at a room temperature 20°C. How much longer is it when it contains boiling water at one ATM pressure

Question

An aluminum bat is 17 m long at room temperature 20°C. How much longer is it when it contains bowling water at one ATM pressure

Answer 1

The relevant equation is ΔL = α x Lo x (t_f - t_i), where α = coefficient of linear expansion for Al (24 x 10^-6) C^-1, ΔL= change in length in meters, L_o = length at 20C.

ΔL = 24 x 10^-6 C^-1 x 17 m x (100 - 20) C = 0.033 m
