Answer:

ΔL =0. 000312 m

Explanation:

Given that

At room temperature ( T = 25 ∘C) ,L= 1 m

$L=1+2.4\times 10^{-5}T$

So the length at 13.0 ∘C above room temperature

$L=1+2.4\times 10^{-5}T$

$L=1+2.4\times 10^{-5}\times 13$

L=1.000312 m

So the change in length

ΔL = 1.000312 - 1.0000 m

ΔL =0. 000312 m
