A metal rod 800mm long is heated from 10^oC to 95^oC. If it expands by 1.36mm, the linear expansivity of the metal is

In this problem, the change in length is already provided as 1.36 mm (or 0.00136 m).

So that's why the instead of L2-L1( the normal formula) they used 1.36

Read the question thoroughly and you will see that the change in length is already given
Thanks

chai this calculation is not correct the formula is (l2- l1 )/L1*T2-T1

Thank you!
I did rubbish using the normal formula (linear exapansivity).
