In a word NO. Vacuum has ZERO heat capacity. It cannot and will not absorb heat under any (non magical) circumstances. Vacuum is a perfect (almost) insulator. That is why they make thermos flasks and cryogenic gas tanks with a vacuum between the layers. It keeps the heat or cold right where it is. I have no physical problem with launching a bunch of stuff into space but it has nothing to do with heat rising in that circumstance. What we would have then is a bunch of superheated steam being forced into space. (Of course you must realize that it would have to leave the geysers at something close to 25,000 miles per hour right?) Now your situation is this. You have millions of cubic miles of superheated steam orbiting the earth. (original 800 degrees plus friction from the incredible velocity at which it was ejected.) When the stuff begins to fall back to earth it now has an additional (massive) ammount of energy stored up as potential energy due to its height above ground. It will release this energy into the atmosphere as it falls. That is one hell of a lot of heat!
There is nothing magical about this. It is a perfectly well understood mechanism that any science undergrad and most high school students could explain to you. The fact remains that you have to put energy into the system to cool the water. The system as a whole, increases in temperature. This is not what happens in our upper atmosphere. If it did then the process itself would fry the earth with its excess heat.

Oh, no problem. A Few Silly Flaws In Walter Brown's Hydroplate Theory. Now, the problem is keeping it in the Solar Syatem and getting it back to Earth. Oh, and it probably took the whole atmosphere with it, by entrainment. But we'll just direct God to do a few more miracles, no worries.

No problem there except the brass still has to fit in a frame of wood and again you have the problem of the swelling in 100% humidity now closing tightly on a brass containing door. And you have no answer for how the animals kept from overheating due to lack of evaporation of sweat.Nor for the waste that the animals produced. Remember this is only a tiny proportion of the difficulties that arise from the flood story. We might also ask of what food did Noah and his family eat and how did they cook it on a sealed vessel?

I was under the impression that water becomes steam only because its under pressure remove the pressure and it cools quite quickly because its no longer under pressure. Please explain black radiation making it not possible for steam to cool quite quickly in the natural once its pressure is removed as in a vacuum as stated in the article that it cools quite quickly to 46 degrees F to a clear chilled water vapor. Explain why I need to keep heating my hot water heater if this black radiation takes so long to dissipate its heat. http://www.energysolutionscenter.org/tech/tech_absorpchill.asp The Hydroplate senerio critic that JonF brought up is a good analogy however it does not mention that the water blasted laterally out from beneath the earth so the water would of not of been necessarily been blasted out of orbit. Here is a different article about the making of snow which hopefully will explain how water vapor coming down from above the atmosphere and meeting with the compressed atmosphere below would produce snow. This explains the rapid glatiation of the northern hemisphere in that what was happening is quite similar to how they make snow in the natural world. http://rabi.phys.virginia.edu/105/2000/ps9a.html The compressed air enters the nozzle at ambient temperature but as it expands into the open air, this high-density air cools dramatically. It is doing work on the open air, pushing that open air out of its way to make room for itself as it expands to normal density and pressure. Doing this work takes away a good fraction of the compressed air's thermal energy, so it becomes quite cold. Heat flows into it from the water droplets and those water droplets freeze into artificial snow. Edited by johnfolton, : No reason given.

Water vapor is clear even at 100 percent humidity, if the temperature is cooler there would not be a problem within the ark given the ark was pitched within and without.
I couldn't find in genesis saying the ark was a sealed vessel, it mentions a window a cubit to fashion it above. Normal air circulation would of supplied fresh clear air from above by the water being diverted away.
If the window was running a cubit the length of the roof was closed but not sealed, then by normal air convection would drive the hot air out and the cooler air within the ark. Edited by johnfolton, : No reason given. Edited by johnfolton, : No reason given.

Oh I see where your misunderstanding is coming from now. Water becomes steam (converts from liquid to gas phase or boils) depending on pressure and temperature. At sea level, (one atmosphere) it becomes steam (gas) at 100 degrees C. If you move it up a high mountain then it boils at a much lower temperature. Put it in a vacuum and it instantly boils no matter what the temperature is. Pressure is the only thing that keeps it liquid. Have a look at the phase diagram for water/ice/vapor
As for the temperature, that is down to the rate of molecular vibration and is independent of pressure entirely. The water molecule can only get rid of its heat (vibration) by passing it on to something else. In a vacuum there is nothing to pass it on too except for infrared low energy photons (black-body radiation) so it will remain very very hot for a long long time. Gasses always want to expand to fill up all available space around them in order to equalize pressures. In space the volume to fill is pretty much infinite so the molecules will continue to move away from each other until they no longer interact with each other in any way. The vast majority of the stuff would never return to earth at all once it gets into space.
because your hot water tank is NOT in a vacuum and can therefore lose heat to its surroundings by conduction. The pipes that come out of it feel hot right? That is conduction.
This is basic physics. Nothing tricky here. and incidentally this is not the entire quote from your site. it makes more sense with the entire thing included. First it asks the question..... quote: then it goes on to answer the question... quote: The jet of air absorbs heat from the jet of water as it expands. In this example the air starts out at ambient temperature (which is actually Zero degrees C) then gives away heat to the surounding air as it expands (by conduction). It then absorbs latent heat from the water to re-equilibrate itself with the ambient temperature. This forces the water to go through a phase change (to ice) but without actually changing temperature at all. As I said, basic physics. (and horribly over-simplified physics too)

If the temperature dropped it would become fog. Nonetheless the wood still expands and has nothing to do with the pitch.It is the reason a gap is left in doorways of your home ,to permit for expansion in high humidity.The humidity aboard the ark cannot fluctuate since there is no where for it to go.
One window does not a circulation make. So even the bible shows that this is not possible. Regardless the 100% humidty would prevent them from lighting kindling as it owuld be saturated after a few days. Edited by sidelined, : added extra comment

It appears that infared energy works quite well for cooling water in these heat exchangers rejecting infared radiation into space. Basically the steamed water molecule in space would be cooling by releasing infared radiation(especially on the dark side of the earth). REMAINING A VAPOR because its liquid state is only based off pressure and not temp with no pressure it remains in this chilled water vapor state until it is pressurized by the atmosphere. In the northern hemisphere being in a winter this chilled water vapor pressurized primarily to snow, the evidence is all the glaciation in the northern hemisphere. In the southern hemisphere based on the lack of glaciation returned primarily as rain. How is there differences in principle in respect to these heat exchangers to the water molecules rejecting infared radiation into space? http://liftoff.msfc.nasa.gov/news/2001/news-stationcool.asp In space, objects heat up by absorbing sunlight and can only cool off by emitting infrared energy, transferring the heat by radiation. First we remove excess heat by this very efficient liquid heat-exchange system," said Gene. "Then we send the energy to radiators that reject the heat into space."

Top creation researchers estimate that Noah could take 55 representative dinosaur 'kinds' onto the ark. If he took less than full-size adults for the largest kinds, everyone could ride in cross-ventilated comfort with plenty of leg room.

I also question that figure. reason being--what effect do all the support beams and everything else needed to support a ship that size on the inside volume. oh, and a All a man's knowledge comes from his experiences
