Heat Pipe - Wikipedia
A heat pipe is a heat-transfer device that combines the principles of both thermal conductivity and phase transition to effectively transfer heat between two solid interfaces.. At the hot interface of a heat pipe a liquid in contact with a thermally conductive solid surface turns into a vapor by absorbing heat from that surface. ... Read Article

Section 15.1 Water, Steam, And Ice - How Everything Works
As a pond freezes, where does the ice begin to form? Melting Ice and Freezing Water When you heat ice, it remains solid until its rising temperature reaches 0 °C. At that point, the ice stops getting warmer and begins to melt. Melting is a phase transition, a transformation from the ordered solid phase to the disordered liq-uid phase. ... Access Full Source

Using Salt And Sand For Winter Road Maintenance
Salt brine solution will stop melting ice and can refreeze at about 20°F, which may require more salt. The ice will not melt or melted snow may refreeze, wasting the chemical. See page 2 for more on spreading rates. Temperature Salt’s effectiveness is directly related to the surface temperature of a snow- or ice-covered road. As temperatures go ... Get Content Here

How does Road salt Work? - CSX Transportation
Salt applied as a liquid or prewet solid can begin to act immediately lowering the freezing point of water. On a pavement where the temperature is 30°F (-1° C), one pound of salt melts 46.3 pounds of ice. One inch of ice on one lane-mile of road would weigh 70 tons. To melt that much ice would take 17 tons of salt. ... Return Document
