If it's zero degrees outside today and it's supposed to be twice as cold tomorrow,?

If you do the math on that same scale, then of course 0 * 2 = 0.

Change scales (kelvin, Centigrade, Fahrenheit etc.) as others have suggested if you really want to do a math problem.

How cold is it going to be? Cold enough to head south for a few weeks.

At 0 C = 32 F

Twice as cold would be = 32F /2 = 16F

It's going to be 16F.

Many people don't know what temperature truly is. Temperature of air is a measurement of the kinetic energy of the average air molecule. This is determined by its mass and velocity.

Twice as cold is like saying half as warm. This means the temperature is half of what it was today.

As others have mentioned, the only "true" temperature scale is Kelvin, which starts from absolute 0 (this means that every air molecule is standing completely still in space).

Here are a few important conversions, for reference

0 C = 273.15 K

0 F = [(5/9)*(0 - 32)] C = -17.8 C = (-17.8 + 273.15) K = 255.35 K

So if it's 0 C, half is half of 273.15 K, which is 136.575 K. Subtract 273.15 to return to C and you get

-136.15 C

If it's 0 F, half is half of 255.35 K, which is 127.675 K. Subtract 273.15 to get to C and you have -145.475 K then multiply by (9/5 + 32) to get to F and you have

-229.855 F

As mentioned, if it's 0 K, you can't get any colder. So only then would it truly stay at 0.

Çonvert from degrees F or C to Kelvin. Then divide by 2.

If you are already in degrees Kelvin, then you are at absolute zero and you can't get any colder.

The Degrees For Today

If it is zero degrees today, and twice as cold tomorrow, then 2x0=0, it will be zero degrees tomorrow.

Not sure what weatherman would say "It will be zero degrees today and twice as cold tomorrow."

mattisan's right, you have to use degrees kelvin. otherwise you would get different answers using farenheit and celsius.

that's a tricky question.

0 degrees celcius is 32 degrees farenheight

using that try and figure out what the temperature will be =]

it will be -30 or -32, something like that, or because it would be in the negatives you could just say 0. hope I helped!
