It will still be zero degrees.
Freezing is freezing... doesnt get any colder... What do I win? |

You do need a point of reference.
But if it is 0 degrees C today then tommorow it will be -17 degrees C If it is 0 degrees F Then it will be -32 degrees F. |

Not true ComputerGuy. You could convert zero degrees Farenheit to Celcius and multiply that times negative two for the answer. The only way this wouldn't work is with Kelvin measurements because zero degrees Kelvin is as cold as cold can get and has thus far proved impossible to achieve. At least this is my understanding of temperatures.

Hot and cold are subjective terms...so, twice as cold as 0 degrees would be a subjective experience unique to the individual.
IOW, twice as cold as 0 degrees may be -1 degrees for a resident of Fiji, or it may be -50 degrees for an Alaskan. |

True in some instances Yankee but it can also be said that cold was used to refrence which way the temperature was moving, thus meaning that the temperature would fall into the negative spectrum as opposed to hot which would indicate a increase in the temperature.

I think your conversions are incorrect. I believe -32 degrees F is 241 degrees K.

Yes, I'm almost positive of it. Let me do some looking. I'm a little rusty on my chemestry right now but I'll find the exact conversions.

But, the other guy isn't correct in the conversions either, I don't think, but, then again, I'm not sure what his point was:
C to F: (9/5*Temperature in F) +32 F to C: (Temperature in F -32) *5/9 C to K: (Temperature in C + 273.15) |

-32 degrees Fahrenheit equals 237.594 degrees Kelvin. The general rule (for 'close enough' situations) is that to convert from Fahrenheit to Kelvin you add 273, drop the F and add a K. That means that 0 degrees K would be in the area of -270ish degrees F, which has never occured in nature and has yet to be duplicated in science. It is a common theory that all molecular motion stops at 0 degrees Kelvin.

No, think about, you reverse the equation and subtract 273 (roughly) from 0, drop the F and add the K. It is actually slightly higher than that but not much.

Quoted: I think your conversions are incorrect. I believe -32 degrees F is 241 degrees K. You're close. -32F = 237.59K Since the Q was ".. 0 deg and twice as cold..." 0 K = -459.67F or -273.15C (x2) -255.37K or -273.0K I Had obviously used F, but while double checking my math and cross checking, I found the anamoly between C and F.. I'll stop here as 0 degrees Kelvin is the point at which all motion in matter stops; it is known as "absolute zero." and theoreticly impossible to go lower than that. [:)] |

Why are there Interstate Highways in Hawaii?
If you're not supposed to drink and drive, why do they check your driver's license before selling you alcohol? Why do you park in the driveway, but drive on the parkway? I wouldn't know about the temperature. It was 117 high 91 low yesterday here in Kuwait. |

I am confused….. So what you guys are saying is that you don't think it will ever be "twice as cold as 0 degrees" in either Fahrenheit or Celsius And we have to switch to "absolute zero." In another scale. In all scales absolute zero Equals -273.15 degrees Celsius, or about -460 degrees Fahrenheit, Or the degrees C plus 273.15, which is Kelvin, Or F plus 460. which is the degrees Rankine, Therefore when we say "twice as cold," we should mean this by it: "half the temperature on the Kelvin (or Rankine) scale." By this definition, "twice as cold as 0 C" is half of 273.15 K, which is 136.57 K. Converting this back to Celsius, we get -136.58 C (or -230 F.) That's very cold.. [whacko] -[smash] [smoke] |

I have developed a coldness scale based on tongue sticking.
Room Temperature: Tongue sticks to anything with super glue on it. Zero degrees: Tongue sticks to polished chrome or Hilary's ass. Minus 20 degrees: Tongue sticks to steel. Minus 40 degrees: Tongue sticks to rough aluminum. Minus 60 degrees: Tongue sticks to girfriend's lips. Minus 80 degress: Tongue sticks to, well, we won't go there. As you can see, it can't get any colder than 80 below. |

A muddled, or misdirected definition is the secret to any good math puzzle (If a hen and a half lay an egg and a half in a day and a half...). So... Was the query a red herring all along (while you were you sitting on the trump card)? [:P] marvl, is the sticky tongue coefficient of 7075 T-6 w a nominally 0.002" thick chromic hard anodized coat of MIL-A-8625E [b]really lower[/b] than type M, class 1 Manganese on HC/MS steel w a 0.000035" thick phosphate coating?

That's not bad reasoning, unless you could attain perfect vacuum. If the surrounding media had sufficiently low density, it is conceivable that a small sample could attain absolute zero and not be reheated by its environment for some time (until an errant molecule bumped into it). As for how to cool it if it's in a vacuum, there are ways to cool things using lasers. Since temperature is entirely equivalent to vibration of atoms/molecules, if you can suppress the vibration of atoms by laser bombardment, the sample will be cooled down. It sounds bass-ackwards, but there has been a Nobel prize awarded for this technique. You're definitely right, though, that cooling something to absolute zero using simple heat transfer just can't work unless the whole universe is at absolute zero. |

Oh come on everyone. It's an incomplete question! It's like trying to solve a math with only one number. 2 + ? = ?
"Cold" is a relative term. It has to have a frame of reference. In some areas, zero degress might be considered warm. Now, this topic is silly. The next one might be twice as silly. How silly would that be? [img]http://www.stopstart.fsnet.co.uk/mica/monk.gif[/img] |
