Mercury stream in space

[swansont]

OK, would you use the same labels for space and the relatively huge pressure at the top of a mercury barometer?

 

What I said at the outset was "Some of the mercury will be lost by evaporation"

Your reply was

"The vapor pressure of mercury is 10^-8 torr at 200K, which is close to Rb vapor pressure at room temperature. We have 1g ampoules of Rb in vacuum that have lasted a decade."

 

 

 

No, that was not my reply. That was my post. I did not quote you; I was not replying to you. I was providing information for those reading the thread, specifically imatfaal, who had asked for more information.
