Is magma considered a liquid or a solid?

Magma is a molten and semi-molten rock mixture found under the surface of the Earth. This mixture is usually made up of four parts: a hot liquid base, called the melt; minerals crystallized by the melt; solid rocks incorporated into the melt from the surrounding confines; and dissolved gases.

At zero kelvin (-273°C) the particles stop moving and all disorder disappears. Therefore, nothing can be colder than absolute zero on the Kelvin scale.
