any material that occupies space (volume) and has mass (exhibites inertia or position)
Has a specific geometric arrangement-set volume and set shape
very close spacing of particles
particles appear to vibrate around fixedd points.
Particles vibrate faster at higher temp.
particles are arranged in a regular repeated patter
solids that lack a definite ordered arrangement
ex:glass, plastic, and powder
does not lose its ordered arrangement completely on melting
move more freely than a solid- "fluditly"
set volume but not set shape (takes on the shape of its container)
resistance to flow
partic les are moving so fast they dont stay close together
no fixed shape or volume
expand to fill container and all available space through the process of diffusion
extremely high temperature matter in which electrons are stripped from the atoms
ex: lighting, sun, flourescent lights, neon lights
