if its cold

if you are using the Celsius scale, zero degrees is actually 273.15 degrees above absolute zero. So, twice as cold would be -136.575 degrees Celsius. Similarly, absolute zero in Fahrenheit is -459.67. Thus, from zero degrees F, twice as cold would be -229.835 degrees F.

You mean Kelvin, but yes :drool:

Asked my daughter today the following question :

if its zero degrees how cold is it if its twice as cold ?

What the hell is twice as cold as zero ?

One answer in my office was -100, i dont think so somehow.

Any ideas ? And yes, I am bored.

 

Thats one of those questions that should be asked at the pub when eveyone's had a couple and the conversation has dried a little. It fits snugly alongside 'What is the meaning of life' and 'The theory of space, time & relativity'.

 

Personally I subscribe to it being a simple calculation in mathematics. We can all agree on twice as much being the initial value added to itself. So we can deduce that twice as cold is the opposite of twice as much, therfore we must subtract the initial value from itself. Since 0-0=0 we are at a loss. Aha but we are not because 0 is the answer. Stick with me on this one.....

 

Convert 0°C to F and you get 32°F. If you then subtract 32 you get 0°F.

 

Therefore

 

Twice as cold as 0°C is 0°F. :D

If the temperature today is zero degrees and tommorrow the temperature is going to be twice as cold how cold will it be?

 

That would depend on what temperature scale you are using. The scale which places zero degrees at the absolutely coldest point is called Kelvin. It has the same degree divisions as Celsius does. "Absolute zero," or zero degrees Kelvin, is the coldest temperature possible. This is the temperature at which all molecules stop all movement.

So, if you are measuring in Kelvin, twice as cold is not possible. (0/2=0) However, if you are using the Celsius scale, zero degrees is actually 273.15 degrees above absolute zero. So, twice as cold would be -136.575 degrees Celsius. Similarly, absolute zero in Fahrenheit is -459.67. Thus, from zero degrees F, twice as cold would be -229.835 degrees F.

 

Note that, due to the different scales in Celsius and Fahrenheit, just as zero degrees C and zero degrees F are not equal, neither is "twice as cold."

Well if 0*C is cold then twice as cold would be ******* cold

 

You could look at it as being relative if the average temp of the last few days was 5*C then when it was 0*C it would be 5*C less than normal so twice as cold would be (5x2) = 10* less than normal which would be -5*C on the scale

No it wouldn't. See above

The fact of the matter is that no matter how you approach this, you will never get a resolve if you use mathematics. Each of the most professional sounding answers you find on the net all state that it depends on the scale you use, be it Kelvin, Celcius, Farenheit etc.

 

Its a bit like the Tempreture readout on my car, sometimes it reads +0 and sometimes it reads -0, how can that be? Yeah I know under 1 degree, but yo uget the point.

 

the human brain can not compute infinity nor can it understand that space is infinite. Everything must have a start and a finish, so whats at the end of space??

 

I think its best just to accept that if its quite simply colder than 0 the folloing day, then its Twice as Cold as the day previous. :D:/:lol:
