the best way to solve this is to transform the unit u r using celcuis or fehrenhit into kelvin.
I will consider its zero degrees celcuis, which equals 273 degrees kelvin.
now it will be twice colder?
then it is 273/2
transfer back to celcuis or fehrnhit.
this is a tricky question since the measuring unit is not stated.
but its always logical to refer to the abolute zero which is zero degrees kelvin.

2 times 0 is 0 so 0

1. What UNITS are those degrees? Fahrenheit or Celsius? 2. What is meant by "twice as cold"? Do you mean half the absolute temperature? Or do you mean twice as much heat flux is leaving your body? Hopefully you don't mean half the absolute temperature, where 0 Celsius is 273.15 K, and thus half the absolute temperature is 136.575 K, which is -136.575 C. THAT IS COLD ENOUGH TO FREEZE YOUR SKIN OFF. Most likely, you mean "twice as much heat flux", because you cannot feel temperature. You can only feel heat flux. This is why you can touch a wooden box and a metal fork and think the metal fork is colder, even though they are both the same temperature. Grossly assuming that the modes of heat transfer off your skin are linear modes of heat transfer, this means that, heat flow off your body is given by the equation: Q_dot = (Tbody - T)/R where R is an assumed constant value called thermal resistance. So: Q_dot_today = (Tbody - Ttoday)/R Q_dot_tomorrow = (Tbody - Ttomorrow)/R Condition of the problem: Q_dot_tomorrow = 2*Q_dot_today Thus: (Tbody - Ttomorrow)/R = 2*(Tbody - Ttoday)/R Cancel R: Tbody - Ttomorrow = 2*(Tbody - Ttoday) Solve for Ttomorrow: Ttomorrow = Tbody - 2*(Tbody - Ttoday) Assuming you meant 0 Celsius, our data is: Tbody:=37 Celsius <<< standard human body temperature; Ttoday:=0 Celsius; Result: Ttomorrow = -37 Celsius

OK. There are a couple of possible answers and it depends upon whether you are measuring in F or C.
One reasonable definition of the term would be to mean that the temperature difference between yesterday and today is the same as the difference between today and tomorrow.
A second reasonable definition would mean that the difference between your body temperature and the air temperature would double. In this case, it will be -37C or -98.6F depending upon which "zero" it was today.
The third reasonable definition would be "half way from here to absolute zero". About -230F or -118C depending, once again, upon which "zero" it was today.

Good question, however the answer can not be derived off of what you provided.
You would need to know WHAT is considered cold by the person who made the statement to begin to figure out, how cold it will be.

0 degrees Celsius? Then it is 32 degrees Fahrenheit. Which means tomorrow it'll be 16 degrees Fahrenheit or -8.88 degrees Celsius.

0 degrees.

The question is meaningless. As a result, no one ever says that.

instead of being 0F outside it will have to be -0F since its twice as cold

-100 degrees...look it up on google
