Hey people in chemistry there are these inverted beaker over porous pot connected to water thingies
what is the principle behind that

<btw my 1000th post on xpc

u mean this

Will the water level always return to normal?

 

[exploded diper]

Will the water level always return to normal?

yeah ....maybe bcuz the diffusion always reaches and equilibrium....so after moving a bit gradually water will return to its orignal position.....

 

[exploded diper]

Where do you use the frequency= 1/f formula? Can somebody elaborate with an example?

f=1/T........T=1/f
t is the time taken to produce one wave...........
f is the number of waves produced in one second.........
so ven u r given a wave say having time of 3 second
thn by formula f=1/T........f=1/3.......the frequency of wave can be noted.....and vice versa.........

yeah

 

[exploded diper]

yeah

so in this u have to see the mr of the gases ... the one with the lower mr will diffuse quickly towards the higher mr gas... in this way u would observe a change in the water level depending upon in which direction the gas diffused...and then it will return bk to its normal height bc diffusion reaches equilibrium (with the gases of different mr equally spread out side and inside the porous pot)....

I never got this right. Like never. Somebody please explain this fully.

dunno why this thing doesnt fit with my concepts
according to me a low pressure zone will be generated as soon as a single molecule is less inside which will make sure that the outer one comes in too
that is what happens in dynamic equilibrium

So what actually happens when the gases of equal mr are in dynamic equlibrium. I mean what happens to water level and stuff?

i think there is something fundamentally wrong with these questions
cant happen in real life like this

Well, you can't get everything. You're imperfect, though.

everybody is
it is our unique level of imperfectness that is perfect

 

[Faizan Muhammmad]

But I mean seriously, this really isnt right
the less dense gas just cant pull water up like that

I believe you would have to get all the mcqs right

Whatever let's cram, okay?
Less dense diffuses first, both gases mix, dynamic equilibrium, changed water level returns to the original.

or get less but they are highest in the world

Seriously man you're a life saver. I never knew this. :O
