Lazy.
scuba tanks are under a lot of pressure, when particles are heated up, they expand and the pressure builds. if the pressure builds to the point of rupture then shrapnel will mess your car up... and if your in it, it will mess you up very bad!

The rails expand during the heat of a summer day.
The thickness of the troposphere typically increases during the summer season due to higher temperatures at the Earth's surface, which cause the air to expand and the troposphere to expand with it. This expansion leads to a thicker layer of the troposphere during this time.
It will expand in Summer as the heat makes the aluminum molecules move faster causing them to expand
No, not all objects expand when heated. Most objects do expand when heated, but there are exceptions such as water between 0°C and 4°C, which contracts when heated. The expansion or contraction of an object when heated depends on its material properties.
Because during summer the weather is warmer and the metal rail lines will have expanded to their maximum length. If they were fixed rigidly in place during cold winter weather when they were later subjected to the heat of summer they would expand and buckle.

The Eiffel Tower is very slightly (i.e., mere centimeters) taller during the summer than during the winter. The reason for this is due to thermal expansion. During the summer, the structure is heated by the sun for more hours during the day, and the warm air of the summer makes it harder for the tower to stay as cool as it gets in the winter. Therefore, the molecules in the structure expand, causing the entire tower to grow by a few centimeters.

Helium is the element commonly used to expand small objects and make them float. Its low density allows it to lift objects, such as balloons, creating the buoyant force necessary for them to rise in the air.
Those are expansion joints. During the changing seasons with varying temperatures, the slabs expand and contract. The spaces allow the slabs to expand without cracking the concrete.
