Need help with physics problem

[Nineshadow]

We have 2 containers , each with the volume of 10 liters , right next to each other. Between them there is a semi-permeable palladium membrane which allows hydrogen to diffuse through it. In the first container there's 20 grams of Argon , at the temperature of 300 K , and in the second container there's 2 grams of (molecular) Hydrogen  , at the temperature of 600K. Calculate the final pressures in both containers.

 

I got somewhere, but not somewhere useful. The main issue is that the temperatures of the two containers are different. It they were the same this problem would have been pretty easy.

sry can't help you only doing my A-Levels right now

I have no particular amount of knowledge of advanced physics, but I'm assuming that the two containers don't contain anything else but their respective argon and molecular hydrogen?

Of course.

[Tedster]

Of course.

So surely the hydrogen should slowly make its way into the container with the Argon and they shouldn't react, leaving no heat in the second container?

The heat should be something like the molecular weight * the temperature of it * the amount of the substance? Then you'd need to account for any heat leakage.

They don't react, yes, but no, the second container isn't left empty.

This process wants to stabilize the pressure in both containers. To the Hydrogen, the second container is like a vacuum. Some hydrogen goes through the membrane into the other container, some remains in the original one. The Argon can't go through the membrane.

But it's not about the heat, it's about the pressure.

I see what you're after now. The heat differences will change the differences in pressure etc.

Since the kelvin scale is absolute, shouldn't it be an exact measurement of heat and 300k should be exactly half of 600k if it's the same substance?

But I don't want to calculate the temperature. I want to calculate the pressure.

And yes, 300K = 600K * 1/2.

[Nineshadow]

@Tedster And for the process to stabilize, the pressures in the two containers don't have to be equal. It's more like the molecular speeds in the two containers need to be the same , but then the temperatures are different so the pressures are different as well.

[Tedster]

But I don't want to calculate the temperature. I want to calculate the pressure.

And yes, 300K = 600K * 1/2.

I want to say that square field theory would apply here but I don't know why. And it doesn't seem to be relevant.

I found a nice wikipedia page!

I managed to solve this problem by backtracking my way with Fick's laws. Still, that's not exactly a solution.

Play Arma 3, it has great physics kappa

It seems people on this forum aren't too experienced with the kinetic molecular theory D:
