    Thermal expansion and coefficient of linear expansion

    The change in length for the rod is 20.11cm-20.05cm plus the expansion of the steel ruler at its 20.11cm mark: ∆L = La∆T = (20.11 cm)(11 x 10-6 /C˚)(270˚C-20˚C)-- u should assume it = 0.055 cm ∆L = (20.11cm-20.05cm) + 0.055 cm = 0.115 cm The coefficient of thermal expansion of the material...
