Can frost form if the air temperature has never been as low as 32 degress fahrenheit```?

Yes.  That's why the evaporator coils of a refrigerator or freezer get frosted.

i never really thought about it and so i was just going to say that temperature doesnt matter because its a vacuum and is dealing with the pressure... but when i thought about it... come to think of it, i do have an answer for you.  the temperature would be zero kelvin, absolute zero.\n\n in an absolute vacuum, the pressure would be 0 if there were no particles, because the more particles you cram into one place, the more pressure there is because p=F/A pressure equals the force of the particles divided by the area of the wall of the container, so with no force of particles(since there are no partiles), the pressure would be zero.  in an absolute vacuum, there are no particles.  Now, if the pressure is zero, then according to the formula PV=nRT (which is just the ideal gas law formula,) if P(pressure) equals 0, i think that means that T(temperature in Kelvin)would also be 0 which would mean that the temperature would be at absolute zero(which is defined as the temperature where all matter stops moving.. not that this would make a difference because there are no particles there because it's an absolute vacuum.  \n\nThis is what i suspect and to confirm my beliefs,  it is consistent with the fact that someone else said that outer space was 3K, and although it's very close to an absolute vacuum, there are a few particles and atoms of gas floating around there, and so it is not quite an absolute vacuum, and the temperature is 3K, meaning it's not quite at absolute zero.  so it stands to reason that since temperature decreases when pressure decreases, that in an absolute vacuum the temperature would be absolute zero, 0 kelvin.\n\ni hope this is a "good answer" and that i made sense while i took you through my reasoning :)

no because cold blooded animals are dependant of the  environment temperature \nif the temperature outside drops to 0 C you would die

If it is for a science project, web sites may or nmay not have the answers....that is all part of a project, to figure it out for yourself, develop your own theories, hypothesis, etc.\n\nI will say it all depends on the temperature....beyond that you're on your own.

If it is 0 deg Centigrade i.e. 32 deg Farrenheit and double the cold i.e. 16 deg F mening -8.9 deg Centigrade

Clouds must form containing ice crystals which combine to form snowflakes - which means the relative humidity is 100% there and the temperature significantly below freezing (0 °C, 32 °F), -10 °C or colder usually. The relative humidity does not have to be anywhere near 100% at the surface (though will increase as snow falls thru the atmosphere), nor must the surface temperature be below freezing - in very favorable conditions can be 45-50 °F (I saw snow at 45° after a cold front October 12 this year, and have seen it as high as 49°). Yet surface temperatures close to or below freezing minimize melting, and if the air is too dry the snowflakes will sublime or melt & evaporate before they reach the ground.\n\nEven if those conditions are met, a significant above freezing  layer - especially in the clouds where the precipitation is developing - is usually sufficient to prevent snow. Even if the surface temperature is well below freezing in such a case, precipitation will usually be freezing rain &/or sleet.\n\nHere is an example from this morning of snow with relative humidity less than 100%:\n\nASUS45 KTFX 301519\nRWRMT \nMONTANA HOURLY WEATHER ROUNDUP\nNATIONAL WEATHER SERVICE GREAT FALLS MT\n819 AM MST THU NOV 30 2006\n\nNOTE: "FAIR" INDICATES FEW OR NO CLOUDS BELOW 12000 FEET WITH NO\nSIGNIFICANT WEATHER AND/OR OBSTRUCTIONS TO VISIBILITY.\n\n* THESE STATIONS ARE NOT UNDER NWS QUALITY CONTROL.

The atmosphere would freeze out on the dark side of the planet. \n\nEven rotating once a year, the greenhouse effect would not be enough to prevent this. Even in Antarctica it can get cold enough for CO2 ice to form during its long dark night. As the CO2 is sucked out of the atmosphere it gets much colder quite quickly. The oceans on the day side would join the frozen air air since as the air pressure dropped, they would evaporate too and the water vapor would meet the same fate. The first cycle would probably take many years to occur due to residual heat in the crust and the amout of time it will take to freeze out most of the CO2 to get the ball rolling quickly.\n\n\nBits of the frozen atmosphere would thaw as it came into sunlight but diffusion would eventually carry anything that thawed to the cold side where it would precipitate out and stick.  I suppose in equilibrium there would be some sort of VERY thin atmosphere, but not much.  I could not tell you how slowly the Earth has to rotate for this to occur. Without ozone, mcuh of the water that evaporates will be photolyzed quite quickly and the hydrogen will mostly escape to space. So the water ice will be lost over time.\n\nSo, you would have a big old mountain of frozen water, nitrogen and oxygen, with less and less water each year on the dark side, and nitrogen/oxygen snows not far from the dayside terminator. \n\nThings are much more stable if the earth is tidally locked to the sun. All the stuff falls on the night side and just stays there.

Half the distance to absolute zero.  Assuming that you are refering to Celsius it is -273.15 degrees, so half of that is -136.575 degrees.

Before it begins to snow, the system begins to cool the air down to ground level.  As this happens, moisture in the ground moves up into the weather system, and eventually mixes with the already cold water, ect within the cloud.  As the snow begins to fall, the temprature drops for a short period of time, and then stabilizes. \n\nThis stabilization happens so that the snow can continue to fall without turning into ice.  On average, winter snow will fall between 14 F and 30 F.  However, it is possible for snow to fall at lower tempratures, however you will see an increase in temprature to have snow fall.\n\nNot all snow falls, however, fall within that temprature range.  Area's such as alaska, greenland, siberia, ect, can have snow even when it is much much colder.  However, the general rule still applies:  snow fall equels an increase in temprature untill a stabilization point has been reached.\n\nSnow that falls within the normal range is usualy wet snow, ie it is snow that is mixed with a bit of melted snow (water vapor), thus causing it to be heavy snow.\n\nSnow that falls below the temprature range tends to be dry snow, ie, snow that has completely frozen over.\n\nDry snow can be a major problem as it doesn't allow for the stabilization to occure at a quick rate, instead, blizzards, huge snow storms, ect, can take effect before the storm system actually stabilizes.\n\nHope that made sens&#92;e

There is little precipitation at the Antarctica because of the low temperatures. Cold air does not hold as much moisture as hot air. In the winter for exsample the humidity is lower than in the summer ( humidity is scale of how much moisture is in the air). Moisture in the air rises and settles in the clouds to produce snow or rain. When the temperature stays as cold as in does in Antarctica little moisture is present to create snow or rain. The snow that is on the ground in pictures and movies that you may see has been there for sometime. There is stays so cold that when snow does fall it takes it a long time to melt. I hope this was helpful.

Literally it would be 0 again... 2 * 0 = 0.\n\nFiguratively I assume he meant from some reference temp.  If it was 10 yesterday and 0 today, a change of 10, it would be twice as cold if it was -10.  \n\nMost of the time it just another way of saying "why do we live where it gets this damn cold"

Dig as deep as you can, unless that would strain your energy. Snow/ice are okay protection (Eskimos survive in igloos), but if the ground isn't frozen, I would try digging because it can be warmer. Ice can't get any colder than 32F, so if the temp outside is below freezing, the ice will be warmer.

Few complex life forms we know of can survive exposure temperatures that low for more than a moment. However, if pockets of milder temperatures could be found (thermal vents, well isulated hybernation dens, etc) some life would likely adapt. Life forms that could mature and reproduce in one warm season (such as a plant that produces spores capable of surviving such a harsh winter) would have a great advantage. Plants such as trees woudn't stand a chance, as is true of many things humans and other complex life depend on for food and shelter. \n\nAnother consideration would be the erosion due to lack of any plants capable of maintaining a root system to stablize soil. Between the turbidity from erosion and likelyhood that all rivers would freeze solid through most of the winter, most life in rivers and lakes would become extinct. Since the upper temperature is not much if any higher than what we have now, the average temperatue is much lower. This would concentrate vast amounts of water in the icecaps, possibly enough to greatly increase the salinity of the oceans, which would also see a major drop in temperature. Most marine life is more sensitive to temperatue changes than terrestrial or freshwater life, so a great number of extinctions there also.\n\nSo no, life would not survive other than perhaps a few simple life forms. Even a drop of a dozen degrees in average temperature would be devastating in the long run for life as we know it.

Hair will freeze at 0 grades Kelvin.\nAnd at the second question it's yes.

temporarily it will be cold and if you have sensitive skin it can itch and turn red since salt makes the temperature go wayyy down, long term is bad because the tmeperatures can get to the negative dgrees, you can definitely get frostbite

of course! as long as there is heat, evaporation can occur. boiling and freezing and melting... evaporation is occuring! and if its below the substance's freezing point, then no. evaporation does not occur when something is soild. as long as there is some form of liquid in the substance, it would turn to gas during the process called evaporation
