Explain this with your "freezing" and "boiling" points, sciencebabs.

Liquid contents at room temperature.
Solid contents at room temperature after 3 minutes of heating have coagulated and cross-linked the proteins. Chemical change.

Boiled = higher pressure (because of the bubbles)
It compresses the liquid into a solid

Protein denaturing. New chains become entangled and thus a solid.

OP's mind is really gonna be blown when he figures out some substances don't have melting points

It depends on the atmospheric pressure more most elements
I'm pretty sure helium is the only one that technically doesn't have a melting point, since it physically can't become a solid

Yeah, it actually isn't that easy
Shit that sublimes can also melt most of the time

I was talking in particular about complex organic molecules, they decompose before reaching a melting point
