Physical Change

Real World Example

Imagine trying to fit a large, fluffy pillow into a small suitcase for a trip. When you compress the pillow to make it fit, it changes in size and shape, but it remains a pillow. Similarly, a physical change involves altering an object's size, shape, or state without changing its fundamental identity, like ice melting into water. In both cases, whether squeezing a pillow or melting ice, the essence remains the same—it's still a pillow and still water, respectively—highlighting that the substance's identity doesn't change despite its altered appearance.
