Expert Solution
Step 1: Freezing point
The freezing point is the temperature required to convert the phase of a substance from the liquid state to the solid state. The freezing point of a solution mixture generally depends on the composition of the solution.
Pure water has a freezing point of 0oC. Alcohol generally has a freezing point value less than that of water.
