particulate nature of matter
matter
all matter are made of particles
brownian motion
invisible particles hit visible ones, seeming as if the visible particle is moving by itself
states of matter
liquid
particles
not as strongly attracted as solid
able to slide past
packed closely
no regular pattern
properties
definite volume
cannot be compressed
lower density than solid
no definite shape
gas
particles
weak forces
move freely
no pattern
far apart
properties
can be compressed
no shape or volume
low density
solid
particles
held together by strong forces
cannot move around
tightly packed
fixed regular pattern
properties
cannot be compressed
high density
definite shape and volume
expansion and contraction
heated
gain energy-expand
increase vibration-cause heat
cooled
lose energy-contract
mass stays the same
mass is conserved
