Final answer:
Stirring cereal as it is added to boiling water aids in the dissolution process, allowing the cereal particles to dissolve more quickly.
Step-by-step explanation:
Cereal should be stirred as it is added to boiling water to aid in the dissolution process. Stirring allows fresh solvent molecules to continually be in contact with the cereal, facilitating the breakdown of its components. The process of dissolution is faster when the solvent is in motion, as it ensures that the water molecules come into contact with the cereal particles, allowing them to dissolve more quickly.
