particles in solids?
fixed
arrangement, only
vibrate
in a
fixed
point,
strong intermolecular
force of
attraction
particles in liquids?
particles
close
(
irregular
arrangement),
free flowing
,
weaker intermolecular force
of
attraction
particles in gases?
random
arrangement, moving at
different speeds
,
weak intermolecular force
of
attraction
density?
number of
particles
in a
volume
pressure?
a
force
on an
area
pressure from a fluid?
when an object is
beneath
a fluid, the fluid
exerts
a
pressure
on the object
below
specific heat capacity?
how much
energy
that required to
raise
the
temperature
of
1kg
of a
material
by
1
degree
how can gas create a pressure?
-as gas particles
move
,
collide
with
container
-creates a
force
= force on the
area
creates
pressure
-as pressure =
force
/
area
increase pressure?
-heat the
gas up
(more
energy
= more
force
)
-decrease
volume
(more
frequent collisions
= more
force
)
-more
particles
(more
collisions
= more
force
= more
pressure
)
boyles law?
wanted to find relationship between
pressure
in container and
volume
of that container
when pressure
increases
, volume
decreases
lord kelvin?
when the
pressure
in
0
and the
particles
are not
moving
, the
temperature
is
absolute zero
absolute zero
=
-273
