What Is the Melting Point of Ice?

The melting point of ice is 32 degrees Fahrenheit. Pure water can exist in the three phases of solid, liquid and gas. Ice is the solid phase of pure water, and its melting point is the temperature at which it becomes liquid water.

Knowing the melting points of different substances is important because it can help identify the particular solid, liquid or gas. For example, the element tungsten, which is a metal, has the highest melting point, which is 6,192 degrees.

Melting points can also establish the purity of a substance. For example, a mixture has a lower melting point than a pure substance. An example of this is the addition of salt to melt ice.
