When things heat up, most solids expand as higher temperatures cause atoms to vibrate more dramatically, necessitating more space. But some solid crystals, like scandium fluoride, shrink when heated — ...

All materials, with some exceptions, expand when they are heated. However, the amount of expansion per degree change in temperature varies depending on the substance. Since structures are made up of ...

When a spatially uniform temperature change is imposed on a solid with more than one phase, or on a polycrystal of a single, non-cubic phase (showing anisotropic expansion–contraction), the resulting ...
