Here's a breakdown:
* Gases: Particles are far apart and move freely, allowing for significant compression.
* Liquids: Particles are closer together than gases, but still have some space to move around. They are less compressible than gases but can be compressed to a small degree.
* Solids: Particles are tightly packed and have very little space to move. They are very difficult to compress.
Think of it like this: Imagine a room full of people. If the people are standing far apart (like gas molecules), you can easily push them closer together (compress the gas). If the people are packed shoulder-to-shoulder (like liquid molecules), you can still squeeze them a little, but it will be much harder. And if the people are sitting in chairs (like solid molecules), there's hardly any space to compress them.
