State | Particle Picture | Arrangement of Particles | Motion of Particles | Other Properties |
Solid | | · closely packed · regular position | · vibrate about a fixed position | · fixed shape · not easily compressed since particles are closely packed · Strong bonds |
Liquid | | · closely packed · no position | · free to flow over each other | · takes shape of its container · |
