Interpretation:

The value of composition of the first solid formed during the solidification needs to be determined.

Concept Introduction:

Freezing is the other name for solidification. Solidification is the phase change of matter which results in the production of a solid phase. Mostly, this phase occurs when the temperature of a liquid is lowered under the freezing point. At the solidification temperature, atoms which are present in the liquid begins to bond and start the formation of crystals.

Interpretation Introduction
