Why does a solid material get longer when it is heated?1 / 10

Heat makes the atoms in the material vibrate more vigorously and push each other slightly farther apart on average, so the material's overall dimensions grow.

Name a familiar object whose size is standardized, and explain why that matters.1 / 8

Many answers work — a light bulb's screw base, a phone charging cable, a sheet of paper, a bicycle tire valve. Standardizing the size means the object works with equipment made by many different companies.
