the particular model of matter
Brownian motion
they move continuously in "zig-zag" pattern
it is caused by uneven bombardment on particles by the invisible molecules in air or water
The Brownian motion gives rise to the particulate model of matter states that
matter is made up of tiny particles which are invisible to our naked eyes
without the help of a microscope
particles can be atoms, molecules or ions
The particles possess kinetic energy
so they are in constant and random motion
The amount of spaces between particles of a substance is different
when the substance is different physical states
The motion of particles of a substance in different physical states is different
temperature is a measure of the average kinetic energy of particles in a substance
when the particles gain heat energy
when the particles gain heat energy
their average kinetic energy increases
hence the temperature increases
When the particles lose heat energy
their average kinetic decreases
hence the temperature decreases
in matter, the particles in all 3 physical states have motion
vibrate at their fixed positions only
vibrate and move about freely in confines spaces
vibrate and move in all directions
the particles in solids, liquid and gases are different in the following ways
their arrangement
the motion
the strength of attractive force between them
the distance/space between each other
The particulate model of matter
attractive force
very strong
moderately strong
weak negligible
arrangement
orderly/regular
disorderly/random
disorderly/random
space
closely packed together
quite close together
far apart
motion
can only vibrate at fixed positions
move about freely by sliding over one another
move freely in all directions at high speeds

liquid
gas
