Hello,
Can some one please tell me if I calcilater this right...
Thank You

I used:
I=LK1(Tf-To)

What is the length of an aluminum rod at 65 degrees celsius if its length at 15 degrees celsius is 1.2 meters?

0.001386 meter

• Physical Science -

The answer you have is correct, but it is the CHANGE in length, not the new length. So, the new length is the old length (1.2m) + the answer you came up with.
