Is adding milk to cereal a chemical or physical change?

Adding milk to cereal is a physical change.

A physical change is a change in the form or appearance of a substance without a change in its chemical composition. For example, when you add milk to cereal, the cereal becomes soggy and the milk changes color, but the chemical composition of both the cereal and the milk remains the same.

A chemical change, on the other hand, is a change in the chemical composition of a substance. For example, when you burn wood, the wood undergoes a chemical change and is converted into ash and other substances.
