Particulate Nature of Matter - Coggle Diagram
Particulate Nature of Matter
Brownian motion is the
random
movement of microscopic particles suspended in a fluid
Particles and drawing
Liquid
Particles are less closely packed than solid
Particles are arranged in a disorderly manner
Particles slide over one another
The attractive forces between particles are strong
Drawing
Must touch both sides
Particles must be the same size and shape
Some in the bottom row must touch the bottom
Must all be connected
Gas
Particles are very far apart
Particles are arranged in a disorderly manner
Particles move rapidly in random directions
The attractive forces between particles are very weak
Drawing
Cannot be connected
Cannot touch the bottom
Particles must be the same size and shape
Cannot touch the sides
Solid
Particles are closely packed
Particles are arranged in an orderly manner
Particles vibrate about in fixed positions
The attractive forces between particles are very strong
Drawing
Must touch the bottom
Must be in orderly rows
Particles must be the same size and shape
Kenetic Particle Theory
Matter is made up of tiny particles that are in continuous, random motion
There are spaces between these particles
These particles attract each other
Observable qualities of the 3 states
liquid
fixed volume
cannot be compressed
no fixed shape
can flow
Gas
no fixed volume
can be compressed
no fixed shape
can flow
Solid
fixed volume
cannot be compressed
fixed shape
cannot flow
The temp. of a substance is a measure of the average kenetic evergy of the particles
Solid to gas: sublimation
eg. dry ice = carbon dioxide which is solid at -78 degree celcius
Gas to solid: desposition
solid to liquid: melting
liquid to solid: freezing
gas to liquid: condensing
liquid to gas: boiling
during a change of state, the particles themselves do not change, and their masses do not change
Diffusion and Osmosis
Osmosis
Same as diffusion, but only for water molecules
Diffusion
It is the
net
movement of molecules from a region of
higher
concentration to a region of
lower
concentration
However, particles will still move in both directions
Eventually, the particles will be evenly distributed
Rate depends on...
Relative mass of particles - lower mass, higher rate
Temperature - higher temp., higher rate
For all particles
