Final answer:
Constant stirring of the test solution does not eliminate supercooling effects. It can help minimize supercooling by providing nucleation sites for the formation of ice crystals.
Step-by-step explanation:
The constant stirring of the test solution does not eliminate supercooling effects. Supercooling occurs when a liquid is cooled below its freezing point without solidifying. It can happen when a solution is cooled slowly and without any disturbance. Constant stirring helps to minimize supercooling by providing nucleation sites for the formation of ice crystals, but it does not eliminate it entirely.
