Today I read a story in the WP relating to the rotation of earths “solid” inner iron core. I looked it up from a different source that confirmed it is solid as opposed to liquid. How can it be so hot and not be molten? Thank you!

The same reason pressure cookers allow you to heat water beyond its normal boiling point. If you put something under pressure you change the points at which in undergoes phase change (solid to liquid, liquid to vapor).
The earths core is extremely hot but it’s also under immense pressure. The pressure increases the melting point of the iron core allowing it to remain solid at higher temperatures
