If it is zero degrees outside today and it is supposed to be twice as cold tomorrow, how cold is it going to b

Answer 1

That is a trick question used by teachers to test the ability of students to spot trick questions.

The meaning of "Twice as cold" is indeterminate.

The question can be made meaningful by including a statement of "standard temperature." For example, if the standard temperature is 68 degrees f. and it is zero degrees f. today and expected to be "twice as cold" tomorrow, then the answer is "-68 degrees f."

But without a stated reference temperature, the question is meaningless. You should get a good score for that answer.

Answer 2

Assume twice as cold means half as warm (that's the only logical meaning). Then just convert 0 to an absolute temperature scale and divide by two. For example, if it's 0 F then you can convert to Rankine by adding 460, divide that by two and get 230, or -230 F. You can do the same thing with Celsius. Of course if you're zero is on an absolute scale, then the answer is still 0.

Answer 3

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

Answer 4

it depends, is that 0 degrees Celsius or 0 degrees Fahrenheit?

0 degrees F is a lot colder than 0 degrees C, in fact if you are cold and you want to warm up quickly just read the other side of the thermometer

Answer 5

It depends on which scale you are using.
In Fahrenheit zero is 32 degrees below freezing therefore twice as cold would be minus 32f.
Absolute zero is 40 below in either scale Fahrenheit or Celsius.

Answer 6

double below zero

Answer 7

you can't double "0"
the answer is "0"
