Particulate model of matter (temperance - Coggle Diagram
Particulate model of matter (temperance
Brownian motion
Particles moving in zig zag motion
Caused by uneven bombardment on particles
Particles have KE so they are constantly moving
Amount of space between particles depends on state
Applies for motion also
By an invisible force
particles gain HE, KE increases, faster
Lose HE, lose KE, slower
Factors
Arrangement
Motion
Attractive force
Distance/space
Factors affecting particles
Attractive force: very strong
Arragement: Orderly/regular
Space: Closely packed together
Motion: Only vibrate at fixed position
Attractive force: kinda strong
Arragement: Disorderly/random
Space: quite close
Motion: slide over each other
Attractive force: weak
Arragement: random
Space: far apart
Motion: move in all directions fast
Fixed shape
Strong attractive holds them together
Fixed volume
Only vibrate at fixed position
Cannot be compressed easily
Particles are packed closely, no space
High densities
Particles closely packed, mass per volume ratio relatively high.
Expansion during heating
More heat, more KE, vibrate faster
Vice versa for cooling
Gas
No fixed shape/volume
Attractive force too weak to hold it in place
Low densities
Particles are too spread out, mass per volume ratio is low
Can diffuse easily
2 more items...
Solids
Liquids
No fixed shape but take shape of container
Attractive force kinda strong can slide over each other
Fixed volume
Attractive force strong enough to hold in place
Cannot be compressed easily
Packed closely together, no space to squeeze
Expansion during heating and cooling
Same as solids
Diffusion
Blue dye moves freely in a liquid
Diffusion happens very fast in gas as particles move very fast
50 mixed with 50= less than 100?
Because spaces between particles different
Smaller particles seep into spaces between bigger paritcles
Total volume is less than 100cm3
