Solid can change to liquid {fusion, melting}| {melting}. Solid-to-liquid state change is at a temperature {melting point} and pressure.
If pressure on melted ice decreases, ice freezes again {regelation, ice}|.
If liquid has no dirt, bubbles, or other crystallization initiators, it can cool below freezing point {supercooling}| without solidifying.
Liquid or gas can turn into solid {solidification}| {freezing} upon heat loss or removal. Solid-liquid state change is at freezing-point temperature and pressure.
about mixture-solidification temperature {eutectic}.
