Question

Quizplus · Accepted Answer

When a crystal is placed in a supersaturated solution, the excess solute that cannot dissolve will begin to crystallize out of solution. This release of energy in the form of heat is known as the heat of crystallization, which explains why the solution gets warmer. Therefore, the best choice is A) supersaturated, as it is the only option that explains both the solidification of the solution and the increase in temperature.
