can we reffered zero degree as no temperature?

Zero degrees Kelvin (but not F or C) is as you suggest no temperature at all. Atoms don't move and there is no thermal energy.\n\nOf course, you can't get all the way to 0K in real life, that I know of. Liquid Helium is about 4K which is the lowest most people ever see.\n\n\n---- \n\nOK so a lot of differences in opinion here. First off, cold is not a temperature. Cold is lack of heat. The scientific definition of temperature (from American Heritage) is: \n\nA measure of the average kinetic energy of the particles in a sample of matter, expressed in terms of units or degrees designated on a standard scale.\n\nSo at the risk of sounding like a lawyer or politician, it depends on your definition of temperature and your definition of "no". But in scientific terms, 0K is no thermal activity.

Well theoretically, above absolute zero. But practically, we can't reach absolute zero, so reactions can occur at any temperature humans can reach. We achieved to reach couple nano kelvins but we still have decades to reach absolute zero, if it is possible.

Are you serious? Every possible temperature is in both Fahrenheit and Celsius whether it's hot or cold. Depends where you live if you use F or C.

273K = 0 degrees celsius therefore water freezes\n\nre jackster: freezing point and melting point are the same\nre kay: absolute zero is 0K at which all particles stop moving .. 273K is not absolute zero

Hot and cold are relative words we use to describe heat sensations.  As such they can not form true ratios.  Is laughter twice as good as sadness?  But in the lab, temperatures must be compared in ratios, such as to solve the perfect gas equation, and absolute temperature must be used.  For example your friend lives 100 miles from Chicago and you live 10 miles beyound that.  If you walk ten more miles farther away from Chicago are you now twice as far away as you were?  NO!  Using absolute values you must walk 110 miles farther away.\n\nFor temperatures, Absolute zero is -273K (minus 273 Kelvin degrees).  That is the temperature at which all thermal energy has been lost for all matter.  (It is like Chicago in our simple example).  Therefore, O Celcius is plus 273K and twice as cold (or half as hot) would be 136.5K or minus 136.5C, which is indeed very cold.  Brrrrr!

You know that he probably didn't mean this in a quantitative sense.  Twice might have meant relative to temperature from the day before, or relative to the mean temperature for this time of year, ...\n\n\nQuantitatively, the term "twice as cold" needs to be relative to some baseline, the fact that it is 0 degrees currently is immaterial: 0 degF = -18degC = 255 degK, so you can't just multiply the value by '2' or you will get different values (the same value, a colder temperature, and a much higher temperature, respectively).

if by o you mean zero then the answer is either \n\ntemperature is less than or equal to -7 degrees \nor greater than or equal to +7 degrees, \n\nif the o is actually an o then \ntemp is less than or equal to (o-7) degrees \nor greater than or equal to (o+7) degrees

lets say the temperature difference between yestar and today (0degrees) is x. then tomorrow's temperature will be '0-2x' degrees.\n\nmore example:\nyest temp    = 10 degree.\ntoday's temp =  0 degrees.\ntom's temp   = -20 degrees.

There is a formula...but this is much easier\n\nhttp://www.onlineconversion.com/temperature.htm

That depends entirely on whether you mean 0 degrees Kelvin, 0 degrees Fahrenheit or 0 degrees Celsius.\n\nOnce you tell us that the answer will be very easy to work out. Only the Kelvin scale allows us to refer to temperatures  as fractions of other temperatures, so any reading will need to be converted to Kelvin with reference to absolute zero.\n\nIt's really not hard to do, but you need to tell us your units.

As for me I think all is persuasive. If you start to count temperature from the point when its length = 50cm you better write: L=50*e^(kt) cm. \nNow (iii): the constant k is valid to be unchangeable in rather narrow range of temperatures, in real physics k depends on t. And after melting the whole business does not work at all. On the other hand the function L=50*e^(kt) says that if t<<0 L is expected to shrink to 0, ignoring the fact that t cant be lower than absolute 0.

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.

theoretically, at any temperature above absolute zero, a reaction can occur.  There are very few reactions that are likely to take place at that temperature, but none that are impossible.

-213.8 °F (brrrr).\n\nTemperature is proportional to the kinetic energy of air molecules in motion. At absolute 0, there would be no molecular motion, which is -459.67 °F. Thus 32 °F is 491.67 °F above absoltue zero.  If the molecules have half the energy as that, I suppose it could be considered twice as cold (half as warm = twice as cold?). 491.67/2 = 245.8 °F above absolute 0 and below 32 °F. So 32 - 245.8 = -213.8 :)\n\nUsing the absolute (Kelvin) temperature scale simplifies this calculation because absolute 0 is 0 K.

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.

Add 273 to your Celsius degree to get it in Kelvins\nK = C + 273\n\nThat's because 0-degrees Celsius = 273-degrees Kelvin. \n0-degrees Kelvin = absolute zero, so you can't have negative Kelvins. \n\nHope that helps

0°C = 32°F\nSo instead of going with 0°C, go with 32°F, so that would be 32 * 2 = 64°F or about 18°C\n\nBut if you are talking about 0°F, which is about -18°C, double that and you get -32°F\n\nSo you either get about 18°C or -32°F
