Webmelting point, temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change. When all the solid has melted, additional heat will raise the temperature of the …

WebNov 17, 2006 · If you leave a bottle of wine in your freezer a bit too long, you will find it chilled but fractured. This common experience is a result of the volumetric expansion by 9% during the water-to-ice transition, which can generate tremendous pressure in a confined space. One may thus expect freezing water to also fracture rocks.
