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

Solid - Paricles vibrate on the spot, least kinetic energy. They have a fixed shape and similar sized particles. They are closely compacted. Strength of the bond is strong. 

liquids - Move and flow over each other. Don't have a fixed shape and takes the shape of the container. Strength between the bond is weaker than with a solid. 

Gases - particles have the most kinetic energy. They don't have a fixed shape when grouped and have no pattern.

·         

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 compressedd since its particles are far apart
