If it is zero degrees today and it's supposed to be twice as cold tomorrow how cold would it be?

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

Still Zero since (0 / 2 = 0).\n\nWhen double below zero is used it is normally just to put emphasis on the fact that it is very cold.

Two times colder, relative to what? It can't simply be two times colder than a specific temperature, you need a reference.\n\nFor the person who answered after me...LOL dude...twice as cold IS half the temperature, or half as warm. Half as cold is twice the temperature, or twice as warm. Because cold is the absence of heat, the term works like a negative. Half as cold wouldn't be a lower temp.

something close to zero

In F, it's -459.39, in kelvin, it's zero, in celsius it's -273

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.

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).

One answer would be to convert 0C into 273 Kelvin or 32 F and then do some multiplication.\n\nBut "cold" is really a subjective measure based on physiology. I suspect if you did a test with actual humans you would find that around -10.6 C feels twice as cold as 0 C.\n\nThat is what this wind chill calculator finds, if wind speed is always zero.

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.

1) Since space is considered an absolute zero temperature (I think) the answer is 340 degrees, since absolute zero is around 240 degrees below zero\n\n2) 100 degrees F.\n\n3) Nitrogen\n\n4) not sure, but I think around 10 minutes\n\n5) Alternating Current, and Direct Current

-40 F or -40 C is a good estimate

One unit kelvin, or 5/9 degree farenheit

Absolute Zero or around 20 K.\n\nMelting point 14.01 K  (−259.14 °C, −434.45 °F) \nBoiling point 20.28 K  (−252.87 °C, −423.17 °F)

double it and add 30 to the celsius temp and you get an rough farenheit temp-for example 30Celsius x 2=60+30=90Farenheit

it would depend. twice as cold as the difference of that temp compared to the whet temp was that came befor it. so it yesterday was 5 degrees f then tomarrow will be -5 degrees f.

kelvin = degree Celsius + 273.15 \ndegree Celsius = kelvin - 273.15

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
