is it safe to assum that the initial temperature of the ice is 0*C?Explain your answer?

no it is not safe to assume ice is at 0C.  0C is just the temperature where ice freezes/melts.  If you were to place ice into a -80C freezer the ice's temperature would be -80C.  For calculating heat...the ice must be heated to 0C then break the enthalpy of fusion (melt a solid), then heated to 100C, break enthalpy of vaporization(evaporate a liquid), then heat till the final temperature. So in the end it is not safe to assume ice is at 0C.

Temoperature wise, Absolute zero is 0 degree Kelvin, which is -273 degree Centigrade.  How high is up is relative to what you are asking.  If it is 1 degree Kelvin it is "up" from absolute zero, but it is still damned cold.

Salt... When applied to ice, the salt (NaCl) dissolves into the water creating a salt water mixture which has a lower freezing point than pure water.\n\n10% salt solution freezes at 20 F (-6 C)\n20% salt solution freezes at 2 F (-16 C)\n\nSalt becomes less effective at temperatures below 0F (-32 C).\n\nEnjoy!

It's impossible to give a quantitative answer of what is "twice as cold" unless you are talking relative to absolute 0 Kelvin.  The quantity of heat in 0 degrees C is 273 degrees K, so technically you could say tomorrow will be 136.5 degrees K tomorrow (I sure hope not since that is -136.5 degrees C or -213.7 degrees F).\n\nThe issue is the scale.  Think about the case of 0 degrees C which equals 32 degrees F.  In Farenheit, you'd say the answer is 16 degrees, but in Celsius you'd say 0.  But that's two different answers depending on the scale.  If I were to create my own scale, you could make the answer anything.\n\nSo the real answer is you can't answer this question.

If the air cools to truly frigid Arctic temperatures such as -40 C and below then the moisture capacity of the air will be so low that likely not much snow can occur. Only at these extremely low temperatures is the phrase "it is too cold to snow" fairly valid.\n\nAt the temperature of absolute zero ( 0 K, -273 C, -459 F) all air including water vapor condenses and loses all molecular energy. The temperature can not cool below absolute zero. \n\nIts can't snow in deep space.......

The answer to this is made tougher by the fact that the water will be freezing.  I mean how can you answer a question where the water is ice cold and use the data provided at STP?  Think you need to either re-read your question or provide a little more info.

It's absolute zero, where there is no heat, and therefore no movement of particles.  It is -273 C.

Nothing.  Temperature is actually the kinetic energy of   countless atoms in a given space.  At 0 kelvin the atoms would stop moving.

First we must use the Kelvin scale as is the only absolute scale starting from 0. You have quantified the amount of cold so you must use an asbolute scale. Kelvin measures the absolute temperature with 0 representing NO kinetic motion whatsoever of the molecules. Kinetic motion is another way of defining temperature. That said here we go:\n\n0 degrees F is ~255K so half of that is 122.5K which is -233.57 degrees F. \n\n0 degrees C is ~273K and half of that is 136.5K which is -136.5 degrees C. \n\nNumbers are all approximate.\n\nAlternatively, you can set an arbitrary definition for cold say 40 degrees F which is 278K. If its 255K (0 deg f)today, then you take the difference between 278 and 255 and multiply it by 2 and you get 46K. Substract the difference from 255 and you get 204K which is -92 deg farenheit.\n\nI hope I didnt lose you yet but I actually had fun doing this ;)!

-15C. I think anything below 15C is cold. Therfore 0C is 15 degrees of cold and -15C is twice as cold.

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

water freezes at 32 degrees Fahrenheit, and 0 degrees Celsius\n\nthe colder the faster

ok so you say its 0 degrees now heres the thing is it in degrees f or c? heres the answers to both. ok so 0 deg. c is 32 deg. f. now to get the temp when its wice as cold of 0 in celsius lets first divide by 2 32f. so then 16f is equal to -8.888888889c.

id say reactions can occur at any temperature above 0k. so 0.00000000000000000000000000000001K, the reaction would happen but really really really really relaly slowly. but thatz in theory. i have no clue bout pracitcally. i think the lowest temp theyve got to so far is either 4K or 0.6K. so ya.

D) It's heat of fusion is higher than its heat of vaporization.\n\nWater's heat of fusion is: 334.5 kJ/kg\nWater's heat of vaporization is: 2256 kJ/kg\n\n\nE IS NOT CORRECT BECAUSE: Water is denser than ice. If water was not denser than ice, ice would not float.\n\nAnd Mr. the_bendude, you must have never taken chemistry. Heat is not the same as temperature. Yes, water boils at 100C and freezes at 0C, but that does not mean those are the heats for which it does.

In addition to the fact that at 4 degrees celcius, water has an absolute density of EXACTLY 1 g/cc, at 0 degrees, it is in equilibrium with its solid phase (ice) which has a density of LESS than 1 g/cc due to its open cage like crystal structure. So, its exact density at 0 degrees is impossible to standardise.

If you mean what temperature on an absolute scale would be 10% of 0 degrees centigrade on that absolute scale, one would convert degrees centigrade to Kelvin by adding 273.15 and take 10% of that, which would be 27.315 Kelvin, or -245.835 degrees centigrade. This is not a naturally occuring temperature anywhere on Earth.\nIf you were referring to the layperson's application of percentage, then you would take 10% of 0 to get 0 degrees centigrade. However, there is no empirical motivation to do this.
