What substances melt at Temperatures close to the Boiling Point of Water?
Substances that melt near the boiling point of water (100°C or 212°F) include wax, gallium metal, and some organic compounds like acetamide. For example, gallium melts at 29.76°C and remains liquid up to 2,400°C. Wax melts in the range of 50°C–100°C, depending on its composition.
These materials are useful in various applications. Gallium is used in semiconductors and thermometers, while wax is widely used for making candles. Melting point variations make these materials ideal for specific uses, including temperature-sensitive applications or phase-change systems for heat storage.
