The answer cannot be -1 degrees, can it? why? perhaps the answer lays in the question.. maybe the question cannot be asked?

no the question cannot make sense....its a good one.....but i will say -136.575°C as it is the half point interval between absolute zero and 0°C....made me think that one

You cannot talk about "half as cold/hot" or "twice as cold/hot" because the zero point of temperatue is arbitrary chosen. The half of zero is zero, but if you convert to Fahrenheit (or whatever scale) you get defferent answers.
Temperature is a measure of the average energy in air molecules. When this energy is zero (zero Kelvin), the temperature is -273 C, so the most correct answer is probably that twice 0 C is twice 273 Kelvin is 546 Kelvin is 273 C. But this is probably not what you meant.

The lowest temperature that can be achieved in a substance is -273,15 degrees of Celsius (this is called absolute zero). Another way of measuring temperature is using the Kelvin Scale. Kelvin’s scale 0 is equivalent to the absolute zero or in other words zero degrees of the Kelvin Scale is equivalent to -273,15 of the Celsius scale. As such, the following formula emerges:
Conversion Formula from Kelvin’s degrees to Celsius:
°C = K - 273.15 (1)
Using this formula one can realise that
(1)
IF C=0 ==> K=273.15
As such, for a temperature of 0 degrees of Celsius or 273 of the Kelvin Scale, the temperature that would be twice as cold as the one mentioned would be 273.15/2= 136.575 degrees of the Kelvin Scale or C=136.575-273.15=-136.575 Degrees of Celsius Scale.

Temperature is measured in degrees which is a relative term that has some mathematical properties but lacks others. There are other examples, if I say I am poor, can I become twice as poor or half as poor? No, not really. I can become even poorer or less poor, addition and subtraction exists in this system but multiplication and division do not apply. Other higher mathematical concepts such as sine or cosine of poor don't have any real meaning either.

O degrees Celcius is So many degrees Farenheit say (for sake of arguement) 34. If the temp is twice as COLD then you are going down the scale so that would be 17 degrees F. Translate 17 degrees F into degrees C and you have your answer...................I think!

To answer this properly you would have to know what temperature it was yesterday and how today compared to yesterday and the day before too.
Really "twice as cold" is subjective so even if it was zero again tomorrow and you felt colder you could say "today feels twice as cold as yesterday"

Well when I was at school, 2 x 0 was 0. You could say that the temperature was x degrees warmer or colder though.

it would be - 2 if it was twice as cold as 0 degrees.

Not this way - first we must define COLD ...a starting point for cold solves this. Zero is not just cold it is freezing and therefore long since cold.
It is funny to see how peoples minds work though.

It's the question. Twice as cold from what reference point?

If it's zero celsius then its 273.15 Kelvin.
So if if twice as cold it must be 273.15 Kelvin divided by 2 = 136.575 Kelvin
= -136.575 degrees C
