·         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

·         fixed shape

·         not easily compressed since particles are closely packed
