Solution
When a substance is heated it expands and it contracts when it cools.
In many industries, there may be a requirement for hot water or molten liquid to be transferred from one place to another through metal pipelines.
In this case, when the hot liquids are transported from one place to another through the pipes, there is a repeated expansion and contraction in the metal pipes.
Due to this continuous process of expansion and contraction, metal pipes may break.
To avoid this situation, metal pipes are arranged in the form of loops in industries.
