5.9 and 5.10 starter

5.9 and 5.10 starter


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


Use the animation to verify your answers


· 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
· Complete the missing words in the table below
· Cut and paste the particle images into the table

State Particle
Picture Arrangement of Particles Motion of Particles Other Properties
Solids closely packed
regular pattern vibrate about a fixed position fixed shape
not easily compressed since particles are closely packed
Strong bonds
Liquids 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
random directions fills its container
can be poured
easily compressed since its particles are far apart
Very weak bonds
