If it is 0* one day and it is twice as cold the next day, how cold is it?

Answer 1

Well zero degrees celsius is 273 K, so half as cold as that is actually just 136.5 K, or -136.5 degrees C.

Kelvin (K) is the absolute measure of temperature.

Answer 2

Well, that's an interesting question. The first answer to pop into my head really didn't make much sense: ZERO - because, obviously, 2 x 0 = 0. But that would mean if the next day was 4 times colder, it would still be zero - and that doesn't make much sense either. So let's make sense - instead of zero C, we'll call it 32 degrees F - now the next day is 16 degrees F and that can be converted to C and with that, we can all live happily ever after.

Answer 3

-10 degrees. To me, -10 F feels twice as cold as 0 F.

Answer 4

Like the first answer says, all you have to do is convert the 0* from whatever temperature unit it is currently in to degrees Kelvin, since it is the only absolute temperature scale (where 0 degrees is absolute zero). Once the the temperature is in Kelvin you can simply divide the number by two to find the answer.

Answer 5

-1 or -2

Answer 6

O* centigrade =32*f therefore twice as cold is 16*f which is minus 8.89*c (thats assuming youre talking centigrade)

Minus 8-89*c =264k

Answer 7

The problem is incomplete. We don't know the starting point to measure the temperature drop down to zero. If the norm is 70 and today it's 0, tomorrow is going to be -70.

Answer 8

As stated from the first person who responded:

-136.5 C translates to -213.7 degrees Fahrenheit

That's cold!

Answer 9

The answers in which they tell you to convert to the Kelvin scale are the correct answers and for the reason stated.

Answer 10

0* since zero times 2 is still zero.
