·         

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
solid		·          closely packed

·         regular pattern

·         vibrate about a fixed position

·         fixedshape

·         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 contained since particles are closely packed

·         Weak bonds

gas

·         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
