    To calculate the change in length of the polymer bar, we can use the formula:

    ΔL = α * L * ΔT

    Where:
    ΔL = change in length
    α = coefficient of linear expansion (specific to the material)
    L = original length of the bar
    ΔT = change in temperature

    Given:
    L = 40 mm
    ΔT = (100 - 20) = 80°C

    The coefficient of linear expansion for the polymer material needs to be known to complete the calculation.
