True, but it also depends on the temperature - there's not a lot of Brownian motion at -135 degF

Concentration plays a part as well as temperature. Take, for example, water vapor: the Brownian[^] motion of the air molecules and the macro movement of air currents keep some of the vapor from freezing out. The concentration of CO₂ in the air is less than the concentration of H₂O, so carbon dioxide cannot freeze out, either.

If you want naturally occurring dry ice, you'll need to head to Mars: during the winter, the colder pole can get as low as −143 C, resulting in a layer of CO₂ snow.

No - it's an effect of a substance's partial pressure at a given temperature (vs. the solid/liquid states with which it is in contact). The materials attempt to create an equilibrium which is the appropriate partial pressure for a given conditions in contact with the solid/liquid source. IF there's not enough of the solid/liquid available to reach the equilibrium state then it all goes into the gaseous state.

An example of partial pressure would be smell of alcohol when you open a bottle: it's boiling point is above room temperature. It has a significant partial pressure and thus alcohol molecules leave the liquid phase and become a vapor above the liquid. If the bottle's closed - it stops pretty quickly. If the bottle's open, it never reaches equilibrium and so all the alcohol evaporates. The partial pressure of a solution (example, alcohol + water) is equal to the partial pressures of each component weighted by its relative molal volume. 100pf thus has a tad more than half the vapor pressure of grain neutral spirits.

The CO₂ could potentially be flash-frozen into the solid state, kept aloft by Brownian motion, and then re-sublime in a vain attempt to reach equilibrium with the atmospheric CO₂. Frosty breath.

Since this is CP, it is unlikely that alcohol would ever be in (1) a closed bottle or (2) allowed to evaporate from an open bottle. The actual situation is better addressed by biochemistry, of which I claim not expertise whatsoever, except, perhaps, with well peated single-malt Scotches

With great planning, you can set a camera in the same place and take a picture of the sun at the exact same time of day; in the resulting composite, the sun traces out a figure 8 shape called an analemma[^]. With even greater planning, you can get a tutulemma[^], an analemma with a total solar eclipse.

A few minutes ago my boss started to shouting at me about an immediate solution for something he ignored over weeks (I have 7 emails to prove it!). When I told him that he can't talk me like that, he took his way and went home!
I'm a pissed - a lot Mad | :mad:

Pissed, why? Now you can work in peace with the boss gone.

It is always a good idea to keep the paper trail when situations like this arise. You are in the clear. Now you can work on the solution in the manner and time it requires. So you will have it done by Friday then?

It was broke, so I fixed it.

I can make up any solution he wish for - but HE must have HIS decisions, that's why HE is the boss.
So why shout for a solution, that in your hands...

1, 2 ,3, 4... I can tell you are still quite upset about this.

Shouting usually means that person has lost control and is angry about it. In this situation it is best to remain calm or walk away. Your boss did wrong by shouting at you but he left before he could do anymore damage. If this guy is usually a decent person he will feel quite bad about this, I would. Hopefully he will apologize and you can move on.

If this is typical behavior for him I would talk to your HR person. If this guy is the owner of the company or some other untouchable, it is time to look for another job.

I certainly hope that this works out for you.

Take it all in stride... you can't get too personal at work. He's probably stressed out and lashed out at you but you can't do the same back (well you could, but it wouldn't get you anywhere). Take a few deep breaths and try to go about your day.

Been there, in a previous job keep Emails so when he's taking a customer on a tour starts to pull you up about something 'Yes, yes, just let me hit print on this' the laser printer fires up and prints out a 'wodge' of paper proving you have been doing your job, telling boss of issue (I even had the mail, I got from the head of personnel to stop bothering him and making him upset I was to tell my supervisor, who told me "tell somebody who cares"((had that one two!))) much red faced bluster and shaking WTF | :WTF:

I hated that firm they almost killed me!
