Tell the person next to you…
· How do particles in move in a solid, a liquid and a gas?
· Describe…
o speed of particles
o relative position of particles (fixed or not)
o pattern of particles (regularly arranged or not)
o size of the particles
o space between the particles
o strength of bonds between the particles

· 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 poured · not easily compressed since particles are closely packed · Weak bonds |
Gases | | · widely spaced · no pattern | · very fast moving |
