Gallium freezing point
WebGallium often supercool below its melting and freezing points. A substance can boil and freeze at the same time. This is called ‘The Triple Point’, and it is a specific temperature and pressure at which the substance can exist as a solid, liquid and gas at the same time. WebOne might thus expect Ga and its alloys to freeze on a cold day. Yet the liquids tend to become supercooled, meaning they freeze at temperatures well below their melting points. Consequently, once melted, Ga and many of its alloys remain liquid at or below room …
