It doesnt matter anyway. The weather reports are never right.

The Farenheit and Celcius scales are both relative, not absolute. This means that 0 is just arbitrary...it does not acutally mean the lowest possible temperature. Beacause of this, doubling or halving the temp. does not actually mean that it is twice as hot or cold-- e.g. 100 degrees is not twice as hot a 50 degrees.

The Kelvin temperature scale is an absolute scale. 0 Kelvins is called absolute zero...at that point all molecular motion stops and it is impossible to get any colder.

Celsius Temp = Kelvin Temp - 273 degrees.

So, to answer your question, If it is 0 degrees Celsius today, then that is 273 Kelvins. If it is twice as cold tomorrow (half as hot) it would be 136.5 Kelvins, or -136.5 Celsius.

The problem is in the wording. You don't get twice as cold, you get half as cold and twice as hot. But you can't take or give half or twice of something from nothing. So jump over to F or K or R and calculate. Did the French invent the C scale? Someone in the metric system did.

You could try converting 0 degrees F to an absolute temperature scale (Kelvins) and then pick a point half way between absolute zero and the converted number. Then convert the result back to degrees F.

a million. What instruments are those levels? Fahrenheit or Celsius? 2. what's meant through "two times as chilly"? Do you advise 1/2 absolutely the temperature? Or do you advise two times as a lot warmth flux is leaving your body? optimistically you do not advise 1/2 absolutely the temperature, the position 0 Celsius is 273.15 ok, and subsequently 1/2 absolutely the temperature is 136.575 ok, it truly is -136.575 C. that is chilly sufficient TO FREEZE YOUR epidermis OFF. maximum probable, you advise "two times as a lot warmth flux", because you could't sense temperature. you could in trouble-free words sense warmth flux. that is why you could contact a timber field and a metallic fork and imagine the metallic fork is less warm, even although they're both a similar temperature. Grossly assuming that the modes of warm temperature move off your epidermis are linear modes of warm temperature move, which means, warmth pass off your body is given through the equation: Q_dot = (Tbody - T)/R the position R is an assumed consistent fee called thermal resistance. So: Q_dot_today = (Tbody - Ttoday)/R Q_dot_tomorrow = (Tbody - Ttomorrow)/R situation of the placement: Q_dot_tomorrow = 2*Q_dot_today subsequently: (Tbody - Ttomorrow)/R = 2*(Tbody - Ttoday)/R Cancel R: Tbody - Ttomorrow = 2*(Tbody - Ttoday) sparkling up for Ttomorrow: Ttomorrow = Tbody - 2*(Tbody - Ttoday) Assuming you meant 0 Celsius, our documents is: Tbody:=37 Celsius <<< known human body temperature; Ttoday:=0 Celsius; effect: Ttomorrow = -37 Celsius

Twice. So...

0 = 0
-1 = -2
-2 = -4
-3 = -6

Simple really.

If it's Zero degrees Centigrade, that's 273 degrees Kelvin.
Half of that is 136.5K or -136.5 C.

as was previously mentioned. 'twice as cold' doesn't really make sense.

The problem with this problem is the question itself. It is NOT a question about weather.

It is mathematical conundrum. Weather forecasters do not talk about being "twice as cold."

Good luck

The concept of "twice as cold" is meaningless.

i know some people will say -2 degrees, but not you , no not you
