A Correct answer
Explanation

This is an exact duplicate of question 91564. The correct answer remains that thermal expansion is directly proportional to length (L). According to the linear thermal expansion formula ΔL = α × L × ΔT, longer pipelines expand and contract more than shorter ones for the same temperature change. This question should be flagged as a duplicate.
