What temperature is twice as cold as 0degrees celcius?

Answer 1

The answer depends on what the temperature scale you use. In Fahrenheit 0 degrees C = 32 degrees F, or if you use Kelvin 273 degrees K. It is like asking what is twice as far is London, It depend on where you are. Your answer would be different than mine. If instead you asked what is twice as far as a 1000 miles we would all get the same answer, and we would all convert to Kilometers the same way. Likewise you could ask what is a temperature change that is twice as much as a 10 degree Celsius change and we would all agree.

Answer 2

Total heat in a body is given by MST.

Q = MST ( we take s is a linear function of temperature in the range )

Now let us take five temperature 270, 271, 272, 273, 274, 275 degree Kelvin. 273 degree = 0 degree Centigrade.
If we increase temperature by 1 degree what happens ?
Our system is the environment where we feel hotness or coldness.
Q271 - Q270 = ms
Q272 - Q271 = ms
Q273 - Q272 = ms
Q274 - Q273 = ms
Q275 - Q274 = ms
Therefore, it is found that if we increase the temperature by 2 degree, it requires 2ms heat i.e. double heat is required or vice versa.
Therefore, if environment temperature falls by two degree we release 2ms heat from our body i.e. we feel twice colder than before.
That is temperature 271 K is twice colder than 273 K or 0 degree.

Answer 4

Since cold and hot are relative to our body temperature, anything above 37 feels hot, anything below feels cold.

0 degrees is 37 degrees less than our body temperature, so double that amount would be 74 degrees less than our body temperature which is -37 degree celsius!

Answer 5

When doing "twice as hot/cold" calculations, you have to use the absolute scale: kelvins.

0°C = 273K

Twice as cold, by which I assume you mean half as hot, is half this:

273 / 2 = 136.5 K

Converting this back to Celsius, we get -136.5°C.

Answer 6

0 degrees C = 273K, so 273/2K, -136.5C

Answer 7

0x0 =0
1x0=0
2x0=0
ERRRRRR nothing3
