Question
The pipes used in the transportation of rainwater to the storage tank should be__________ resistant.
- IR
- UV
- MW
- XR
Hint:
If the pipes are exposed to sunlight for a long period the pipes will become weak.
The correct answer is: UV
- The pipes used in the transportation of rainwater to the storage tank should be UV resistant.
- Prolonged sunlight exposure leads the polymer chain reaction to weaken leading to weakening of the pipe wall and disintegration of the pipes.
- So, the correct option is b.
