Look at the diagram. Why do you think there are gaps between the metal connectors on the bridge?
To allow water flow during a rain storm.
To allow air flow during a wind storm.

tightly , increases
loosely , decreases
loosely , increases
The diagram shows an iron ball before and after being heated.
Why can the iron ball not fit through the ring after heating?
