Example:
Imagine trying to fit all your groceries into a single paper bag, but realizing you need to rearrange them to make everything fit. This is similar to a physical change, where the items (like ice melting or clay being molded) might change form or arrangement, but remain the same at their core. Just as the groceries are still the same groceries no matter how you organize them, a physical change involves altering the size, shape, or state of a substance without changing its identity or composition.
