Why is soggy cereal a physical change?

Here's why:

* The cereal itself remains the same: The cereal grains, whether it's oats, rice, or wheat, don't change their chemical makeup when they absorb milk.

* It's just a change in state: The milk simply changes the texture of the cereal by adding moisture and making it softer. The cereal and milk are still separate substances, just combined in a different way.

Key difference between physical and chemical changes:

* Physical Change: Changes the appearance or form of a substance but not its chemical composition.

* Chemical Change: Creates a new substance with different properties.

Examples of Chemical Changes:

* Burning wood

* Cooking an egg

* Baking a cake

In contrast, soggy cereal is a reversible change. You can dry out the cereal and restore it to its original state (though it might not taste the same).
