Q:

What are the boiling and freezing points of lithium?

A:

Quick Answer

Lithium has a boiling point of 1,342 degrees Celsius and a freezing point of 180.5 degrees Celsius. Due to lithium's high freezing point, it exists as a solid at room temperature.

Full Answer

The freezing point of lithium is the same as its melting point. It is where the solid and liquid phases of lithium exist in equilibrium. While lithium's melting point is very low compared with many of the transition metals, it is the highest of any of the alkali metals. For comparison, sodium has a melting point of 97.7 degrees Celsius, while hydrogen has a melting point of negative 259.1 degrees Celsius, which is close to absolute zero.

    What is the melting point of water?

    A:

    Melting point is the temperature at which a solid melts to become a liquid. Since water is already a liquid, it does not have a point at which it liquefies. Frozen water is called ice and has a normal melting point of zero degrees Celsius, according to Purdue.
