Can someone answer this question?
 

If it's zero degrees today, and it's going to be twice as cold tomorrow... what will the temperature be?

-2 i predict

There is no such thing as "Zero" degrees.

Our perceptions fool us but the truth is "0" is a rough estimate of anything.

Here's a guess: 0 degrees fahrenheit is -17.78 celcius.

-17.78 x 2 = -35.56 Celcius

-35.56 Celcius = -32.01 fahrenheit.

What do you think?

Just looked at my answer and it does make sense. Since 0 degrees is 32 degrees below freezing, another 32 degrees subracted would be -32.

:thumbsup .. you are pulling the gfy iq up!! :pimp

Actually, until you define the temperature at which "cold" starts, there is no correct answer for this question.

I buy that! Good work! :thumbsup

If you apply:

you get -12 degrees F

Suppose we double the temperature at fixed volume. The pressure doubles. Then suppose we let the volume change to recover that original pressure (while retaining the doubled temperature). Since that requires the pressure to now decrease be the factor of 2, the volume must (by Boyle's Law) increase by that same factor of 2

So pressure increases DIRECTLY with temperature (in a fixed volume). Or P=(constant)*T.

Perhaps I should elaborate:

If it was 32 degrees yesterday and it is 0 degrees today, "twice as cold" would be -32 degrees

If it was 70 degrees yesterday and it is 0 degrees today, "twice as cold" would be -70 degrees

"Cold" is a perceptual variable and therefor has no fixed value, so until you assign it a value there is no correct answer.

Easy - its the temp at which the balls retract and/or nipples can cut glass.
