| ice | 1. Water or other fluid frozen or reduced to the solid state by cold; frozen water. It is a white or transparent colourless substance, crystalline, brittle, and viscoidal. Its specific gravity (0.92, that of water at 4 deg C. Being 1.0) being less than that of water, ice floats. Water freezes at 32 deg F. Or 0 deg Cent, and ice melts at the same temperature. Ice owes its cooling properties to the large amount of heat required to melt it. 2. Concreted sugar. 3. Water, cream, custard, etc, sweetened, flavored, and artificially frozen. 4.

| ice pack | A cold local application to limit or reduce swelling in recently traumatised tissues; usually in the form of a water-impervious container for ice.
