Oxygen toxicity can occur at much lower pressure when diving. What is Oxygen Toxicity? For diving using regular air the recommended limit for safe recreational diving is 130 ft or 4.93085 ata. This higher pressure than in the previous quote is considered safe when following guidelines for length of time at depth, the pressure being less of course as the diver is ascending or descending. Oxygen Toxicity and Scuba Diving The breathing aside and more to Moonntan's point I think, very high pressures do not directly kill humans by damaging tissues. An exception might be in the early days of helmet diving when a diver could be rammed up into his helmet if the air line broke near the surface. In such cases they could be buried in the helmet.

Saturation diving uses an oxygen/helium mixture to avoid oxygen toxicity as well as nitrogen narcosis. See link above on saturation diving. The extreme opposite would be staying alive in a vacuum which might be possible -according to the following article- for a brief few minutes. Survival in Space Unprotected Is Possible--Briefly

I think seldom of cheerleaders. Cheerleading should be considered athletics. I had kids and they did not ask to be cheerleaders so I did not have to decide if I would let them. Most of the cheerleaders I met in my high school were honors students. I graduated early and have never again seen any of the cheerleaders that I knew.

Damn! Missed the bus again. Was out in the garden and felt a little more of that digital rain. Cover is in place, temperature 77ºF, relative humidity 49%, and barometric pressure 29.57 inches of mercury and steady.

This morning at the 3 day mark -10:45 am- the salted water level was down 3.1cm and the pure water level was down 3.2cm. Some arcs of precipitated salt crystals remained on the glass and are now above the water level. Last night at 8pm clouds were rolling in and the relative humidity rose to 46% and temp was 85ºF. Currently 75ºF, relative humidity 48%, barometric pressure 29.6 inches of mercury, and overcast sky. Addendum: 3:20 pm Pacific Didn't plan on another update until tomorrow, but one of the boys just told me we had a trace of rain this morning before I got up. Rather than stop the experiment -and presuming any precipitation would fall more or less equally into the jars- I put a cover directly above the setup in case more rain falls. Both jars are still open to the air and all light save for directly above. At my latitude -~45ºN- the Sun is never directly overhead anyway so it should be fine. Will remove it when chance of rain has passed. As it is the sky currently remains overcast, temperature is still 75ºF, relative humidity 48%, and barometric pressure 29.57 inches of mercury. On a side note, I'm using an electronic weather station for my readings and all this has me wanting a more advanced model that connects to my computer and also has an anemometer and rain gauge. I do have an analog rain gauge, though nothing of what fell this morning was in it.

Yes - An affirmative term used by astronomers when asked a question. Also an expression of delight or happiness, e.g. when Philae landed on Comet 67P/Churyumov-Gerasimenko some controllers exclaimed "Yes!".

The board purportedly uses electromagnets, i.e. it is battery powered. The exact specifications remain a company secret.

Second - A unit of time based on the rotation of Earth equal to 1/86400 of a mean solar day. Also a measure of latitude and longitude equal to 1/3600 of a degree and commonly denoted an arcsecond.

I will continue the experiment until the jars are dry or it rains & report the result. If the salty water jar level differs from the pure water I will report it. At today's measure and report, nearly half the water had evaporated so the salt concentration -whatever it was- has nearly doubled and yet the salty water continued to evaporate at the same rate as the pure water. John has already covered the high humidity and if the humidity rises I will report it.

53 hours have elapsed and both jars are down 3cm. Mid-morning the relative humidity dropped to 38% and stayed there, high temp was 96ºF and the barometric pressure has remained steady @ ~29.50 inches of mercury. A small arc of salt crystals again formed on the glass.

Saturation dives have been done to over 2000 feet underwater where the pressure is over 900psi. Pressure by depth calculator

Here page: Unobtainite flux-capacitive magnets I am joy to meat this.

No, no, no. Acme Corp. supplies Wile E. Coyote from the Roadrunner show. As noted in the article I linked to, they started out making anvils. Unobtainite flux-capacitive magnets. You're welcome.

That observation is not contrary to what I said; it's in perfect agreement with what I said. What I said was that If the humidity is high enough then water will condense into the solution; the pretty obvious corollary is that if the humidity is low then the water will evaporate from the salt solution. It did. You might want to try again with a saturated solution of calcium chloride and see what happens. Whatever you say John of course. You are free to conduct your own experiment. I have conducted my experiment as described in the OP [and title]: My result at this point is that there is no difference in the rate of evaporation.

Yes, I am clear. Your assertion has nothing to do with my experiment so your assertions are contrary to my 37% relative humidity, i.e. opposed in character. You have made no assertion about what would happen in my experiment. Perfectly clear, thank you. Thank you Sensei. I made do with what I had on hand. By all means carry it out and report back. As the experiment was laid out in the OP, do you have an assertion on the result? Yes I understood, but I had the time and the OP described bowls sitting out in the Sun. I have no such scale. As I commented earlier, "heavily" is a somewhat ambiguous term. One could (should?) conduct a series of experiments with varying concentrations. As to my teaspoon it was a standard type used in cooking. The salt was a courser grain than the usual "table" salt so your estimate of mass may be high. . PS Just checked experiment and overnight the salt that had crystalized on the jar went back into solution. Temperature overnight dropped to a low of 62ºF. Temperature now 70ºF, relative humidity is 52%, and barometric pressure is 29.64 inches of mercury.

Can you clarify your definition of "everyone". Yes. My experiment is contrary to your post because my relative humidity was 37% and not 75%. Swans seemed to say the saltwater would evaporate slower, all else being equal, so my results are contrary to that. Elite Engineer made an unqualified 'bowl without salt will evaporate first' so again my results are contrary. While I am in accord with Sensei's advice to do the experiment, he did not actually do it and made the setup rather more complicated than it need be. Half credit to you Sensei. So, everyone qualified. Will get a photo later tonight as promised. I went back and measured the height of the jars @ 6.5cm, so after a day ~15% of the water had evaporated from both jars. Temp was 98ºF and relative humidity 38% when I checked an hour or so ago and we've had a light breeze. Time elapsed, 33 hours. Both levels down ~2.1cm.

I'm no chemist so I can't say, but my results are contrary to everyone's claims so far. Damanble experimenters!! There are some salt crystals being deposited on the jar now as the level drops. What with the clear glass and bright light I can't get a decent photo right now so will get one tonight. I thought about putting a drop of food color in each for some contrast but decided that would not be kosher midway. To clarify, I didn't weigh anything, rather measured by volume.

Good grief! Fortunately it's not as complicated as you make it out and I'm not too lazy. Cross posted. You're welcome. Got the grandkids interested too. Not our typical weather here in the Pacific Northwest fo sizzle. Records falling left and right. One other note on the experiment, the jar with the salted water has little bubbles all around on the glass. I thumped it a few times but they won't dislodge. While minute, they surely make the level a bit higher.

So 24 hours and the levels are virtually identical; both down 1cm. For reference I think these are 8 oz jars and I used distilled water. Here's a pic at start: A few of additional notes: I used 'sea salt' as that was what I found in the cabinet. I point out however that all salt is ultimately sea salt and even among the marketed 'sea salts' there is no consistency. See sea salt @ wiki. I rather expect there would be little difference in the experiments due to the salt 'type'. As to 'heavily salted', the concentration will get higher as the water evaporates and so making the distinction even more ambiguous. We hit 100ºF yesterday on my thermometer and expect the same for today.

I put two small bowls filled to the brim with water out 5 hours ago, one with 4 teaspoons of salt. Currently 98ºF & 37% humidity. Evaporation from both bowls appears equal with both down ~3/32".

Yes; wind causes an increase in evaporation. Here's how professionals measure evaporation rates: Evaporation Pan Pan Evaporation @ Wiki Class A evaporation pan

G'donya. By any translator, it is widely accorded as the oldest written story extant. There are a number of free online versions as well.
