* Helium alone cannot leak IN without argon.
Complete nonsense !
Helium has an enormous diffusion rate through Pyrex glass.
Argon has almost none. Check the MIT site if you want a source.
* First, he was not using Pyrex glass; he used steel collection
flasks.
For the collection flasks he could have used anything. It was too late.
Helium diffuses into the electrolysis cell itself during the operation.
Second, whatever the diffusion rate for the different gasses
may be, for different materials, it is constant.
No. Again – please try to understand Grahams Law. Apparently you have never
heard of it before now.
Diffusion is based on amu. Argon is 10 times heaver than helium and it
diffuses much more slowly through a material - when both can be diffused.
However, argon does not diffuse into Pyrex at all and helium does.
