Solid

Real World Example

Imagine trying to pack a suitcase for a trip, but every time you think you’ve got it all sorted, some of your clothes seem to change shape and size. This situation is similar to understanding why solids have a definite shape and volume, unlike clothes that might shift around. Just like the perfectly folded clothes that stay in place and maintain their space in the suitcase, solids are composed of tightly packed particles that stay firmly in position, giving them a consistent shape and volume regardless of the container they are in.
