At what temp will spit freeze before it hits the sidewalk?

around -50 celsius like in siberia the threads of your boots snap and spit freezes before it hits the ground like a pellet

Mercury freezing point: -38.72 degrees C\n\nA mercury thermometer will probably lose accuracy somewhat above the freezing point, because as one approaches the phase\ntransition from liquid to solid, one loses the linear dependence\nof the column length on temperature.\n\n\nAlcohol's freezing point is -117 degrees therefore it doesn't get cold enough to freeze alcohol.\n\nTherefore alcohol is better at low temperatures

very cold!!!!!!!!!!!!!!!

Gets cold, freezes.  Maybe cracks.

in theory, when the temp reaches absolute zero everything freezes and is -459.67 degrees F.  temps within a few billionths of a degree have been reached but the materials used in the experiment took on nontraditional states.  at the temp all molecular motion would cease so it would be impossible to reach the temp exactly.

The answer is either 0% or 100%. If ice is 0 degrees C it will remain as ice. [in theory]

It will snow when temperatures are at 32F or below and when their is sufficient moisture in the atmosphere.  It will hail at many different temperatures when the hail rises then falls, rises with air currents then falls when gravity overcomes the aircurrents.

Wait until the icicles are hanging off the end of your nose!I've had my heat on for some time now.Usually set between 65-70.But i live in a tri-level house so the temps very from level to level.

It's a figurative language because it's not actually 100 degrees below zero, just cold enough that you'll be nippy if you go out.

Taking the question in a simple way, if the liq. N2 was at the midway temp. of  -150 deg. Cent., (liq. N2 ranges from -100 to -200 deg. cent.), the banana could roughly take 30-40 min., with all the ice-wool formation in the air, then melting of the snow, then catching up with the room temp. This is from experience. To have a scientific estimation though, you need to consider N2 temp., room temp, mass of the object, shape of the object, other factors like air currents if any, and  also any radiation present.

Depends on pressure/altitude.  At sea level its about 100C or 212F.

Mmmmm, methinks this is a trick question but I will guess at minus 2 degrees...;

The freezing point of pure water is 0°C, but that melting point can be lowered by the adding any solvent such as a salt. Depending on the amount of salt the freezing temperature of a saline solution can range from below 0°C to -21.1°C. The frozen solution is a mixture of separate NaCl·2H2O crystals and ice crystals, not a homogeneous mixture of salt and water. This heterogeneous mixture is called a eutectic mixture. \nThe use of ordinary salt on sidewalks is effective because it requires a colder temperature to freeze water and it is a cheaper alternative to other solvents or methods of ice removal.

In Saratoga Springs, NY where it can get very cold (and Olmpic Speed Skaters have competed on an oval rink) the ground is sprayed with water and allowed to freeze in a natural shallow basin that was bulldozed into an oval track with land in the middle.  Water can then be sprayed on top of the original ice layer to thicken it without melting through.  When the ice layer is thick enough, the entire area can be slowly flooded.  The water used is at groundwater temperature from a hydrant using a fire hose.  I believe that groundwater is about 46F here but will vary from city to city as it is basically the average temperature of all the water that seeps into the ground during a typical year.  The lowest temperature of drain water is of course 32F.  Thus the water is only 14F warmer than the ice being layed down and it must be well below freezing to prepare the rink.  A hockey rink could be built the same way by omitting the land in the middle; but it would require more water.\n\nOf course, ice rinks can be located on a lake or pond if it freezes thick enough.  The NY State Park here has a special rectangular rink that merely requires flooding for figure skating and recreation.

32 degrees F\nor \n0 degrees C

The temp has to be 32 F. or below for it to snow. Look at the weather to find out the chances of it snowing.

Rubbing alcohol contains 70% 2-propanol which has a very low freezing point of -88ºC.\nRubbing alcohol will also freeze, but at a higher temperature of about -32ºC. A normal freezer only gets as cold as -10 to -15ºC. Dry ice (which is usually around -60ºC) is a good way to freeze it. \nHope this helped.
