Can some one please tell me if I calcilater this right...
What is the length of an aluminum rod at 65 degrees celsius if its length at 15 degrees celsius is 1.2 meters?
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.
