· 5.9 recall that particles in a liquid have a random motion within a close-packed irregular structure
· 5.10 recall that particles in a solid vibrate about fixed positions within a close-packed regular structure

State | Particle Picture | Arrangement of Particles | Motion of Particles | Other Properties |
Solid | | · closely packed · regular pattern | · vibrate about a fixed position | · fixed shape · not easily compressed since particles are closely packed · Strong bonds |
Liquid | | · closely packed · no pattern | · free to flow over each other | · takes shape of its container · can be packed · not easily compressed since particles are closely packed · Weak bonds |
Gas | | · widely spaced · no pattern | · very fast moving · random directions | · fills its container · can be packed · easily compressed since its particles are far apart · Very weak bonds |
