If the temperature is zero outside today and it's going to be twice as cold tomorrow, how cold will it be?

Answer 1

Bloody Freezing!!!

Answer 2

The term "twice as cold" does not have a well defined meaning. It could mean the absolute temperature, in which case the temperature tomorrow will be -137 C or -230 F, but as you can see that isn't plausible.

Answer 3

Cant be twice as cold since cold is a negative, ie absence of heat. It can be half as warm. To find the answer you will need to calculate in degrees Kelvin (Absolute). Add 273 to todays temperature in degrees Celsius and didvide by two. This will give you an answer in degrees Kelvin. To convert to Celsius minus 273 from that answer.

Answer 4

"Twice as cold" doesn't have any real, physical meaning, because it's the inverse of a measurable amount.

It's the same as describing one piece of string as "twice as short" as another - it may be half as long, but who's to say it's short at all? It depends what you were going to use it for.

So if you want to try to define it mathenatically, I suppose you should say it's the temperature that's twice as far from what you'd expect: so if we expect 15 degrees at this time of year and it's zero, you could say that -15 degrees is twice as cold!

Answer 5

If it is going to 'feel' twice as cold tomorrow then we should benchmark on the average human body temperature (37 deg). If the temperature today is 37 deg lower than human body temperature and tomorrow it will feel twice as cold, then tomorrow it will be minus 37 deg.

Answer 6

Since zero Kelvin is when all kinetic energy ceases, then that is as cold as it gets.

Thus, since temperature is a measure of kinetic energy, then all relative measurement of energy should start at zero K.

So, if it is zero Fareinheit (-18 C or +255 K), then half of that energy amount (twice as cold) would be +127.5 K) or about -145.5 C or about -230 F.

If it is zero Celcius (+273.15 degrees K), then half of that energy amount is about +136.6 K or about -136.6 C or about -214 F.

And of course, half of zero K is still zero K or -273.15 C or -459.7 F.

Answer 7

Cold enough for me to stay in bed!

Good question though - let's hope someone can come up with the right answer.

If your question relates to 'zero C', then is the answer 'zero F'?

Answer 8

Anything below O degrees is cold. It don't feel any colder if it's -12 degrees. Once it is so cold who cares stay inside.

Answer 9

Twice as cold is not a valid concept.

Answer 10

Double zero?
