Length of copper wire = 150 cm = 1500 mm
Temperature initial (Ti) = 30
Temperature Final (Tf) = 130
change in temperature = 130 - 30 = 100
change in length = 2.55 mm
change in length / actual length = coefficient of linear expannsion * Change in temperature.
2.55/(1500 * 100 ) = coefficient of linear expansion.
coefficient of linear expansion. = 0.000017 = 1.7 * 10 ^ -5

We know that the change in length of wire is,
l'=lαT
where l' is the change in length
l is original length
α is the coefficient of linear expansion
and T is the change in temperature.
Substituting the values,
2.55x10-3 = 0.150 x α x 100
Hence, we get
α=1.5x10-4
