    229.835 degrees below zero (Fahrenheit).

    0 degrees Fahrenheit is 255.372 degrees Kelvin. Relative to absolute zero, and "twice as cold" meaning "half as warm", the answer would be 127.686 Kelvin, or -229.835 Fahrenheit.

    That's cold.

    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

    Well 2 x 0 is 0 so my guess is 0

    Good question, but I'll say 2 degrees below zero.
