Question

what is brownian motion? How is it related to colloids?

Answer 1

Brownian motion is an important property of colloids.

In colloids, the particles of the colloids are in completely random zig-zag motion. This zig-zag motion of the colloidal particles is called Brownian Motion.

Answer 2

so how is that differentiating colloids from solutions and suspension? @midhun.madhu 1987

Answer 3

lol why is this in chem section

Answer 4

colloids are related to chemistry, buddy

Answer 5

Answer 6

thanks @dan815

Answer 7

can you gimme some details about colloids maybe i can help you link brownian moton to it

Answer 8

colloids are heterogeneous mixtures

Answer 9

the particle size varies from 1-100 nanometer

Answer 10

i have doubt is the particle size between 1-100 nanometer or 1-1000 nanometer?

Answer 11

ok from what im reading it looks like a colloid continues to have particles dispersed evenly, not in a settleed state

Answer 12

meaning there is some minimum average kinetic energy being maintained in the mixture

Answer 13

so what makes it different from solutions and suspensions?

Answer 14

this can be explained with brownian motion as therees a constant collisions occuring throughout and theres random motions of paricles taking all over the place, keeping the kinetic energies alive

Answer 16

suspensions is more like dust

Answer 17

or fog

Answer 18

colloids have particle size between 1-1000 namometer

Answer 19

am i right?

Answer 20

its in a transiltion state, like dust clouds and fog will eventualy settle after the kinetic energy in the system settles down

Answer 21

ya and the moelecules in question are bigger

Answer 22

fog is actually colloids

Answer 23

oh i thought suspension is a type of colloid lol

Answer 24

no... suspension is different from colloids

Answer 25

but Fog does settle eventually

Answer 26

it eventually creeps down and disperses, but theres a change in state

Answer 27

colloid particles do not settle down

Answer 28

oh i see
A colloid is intermediate between a solution and a suspension

Answer 29

i understand so this middle stage is what is called the colloid

Answer 30

i think that makes it different from solutions and suspensions

Answer 31

fog eventually transitions into water droplets and thicker water vapor which will eventually fall into suspension and solution states

Answer 32

oh no

Answer 33

how?????

Answer 34

okay scratch all what you two have been discussing so far

Answer 35

it pains me to see this continue LAUGHING OUT LOUD

Answer 36

ok

Answer 37

okay explain pls nin

Answer 38

ive been bsing my way every since colloid hehe

Answer 39

he is concerned with solutions

Answer 40

me?

Answer 41

no he wants colloids

Answer 42

what?!!???

Answer 43

Fog in the state it is, is a colloid so u can rest assured

Answer 44

okay that needs rephrasing

Answer 45

particle size varies from?

Answer 46

its given in that post

Answer 48

one medal for you @dan

Answer 49

there are too many links being given

Answer 50

plz fan me too im a cute lady

Answer 51

pls give me a medal also

Answer 52

if nin gave his medal properly we can all have a medal but nooo some ppl are too greedy

Answer 53

hahaha..

Answer 54

dan, let us create a program utilizing brownian motion and this colloid rubbish

Answer 55

u want a simulation ?

Answer 56

random random random

Answer 57

dont say colloids as a rubbish

Answer 58

did you do this already? I know simulations of brownian

Answer 59

everything is rubbish

Answer 60

no

Answer 61

even rubbish is rubbish

Answer 62

then we could have changed the definition of matter and say:
" Everything in this universe is rubbish"
instead of
"Everything in this universe is matter"

Answer 63

actually what is cool about this question is that it reminds me of my stats

Answer 64

lol

Answer 65

gotta love them stats

Answer 66

oh ya heres a fun question

Answer 67

given volume V, and avg kinetic energy of K and particle of size P, and n particles, what is the probability of collision over time

Answer 68

so this seemingly randomized are not random at all, but normalized LAUGHING OUT LOUD
wow gotta love this statistics rubbishness

Answer 69

that is too high for me dan

Answer 70

it's similar to your question, melo

Answer 71

in the end, the bell curve equals to 1

Answer 72

quite an interesting question

Answer 73

i am back guys

Answer 74

i am going to close the question
thank u people
