This is an old math riddle. Mathemeticians and physisists like to refer to absolute zero (Kelvin scale, with no negative numbers), instead of Fahrenheit or Celsius (which are relative to the freezing and boiling points of water at sea-level).
Technically, in a relative scale it makes no sense to speak of doubling or halving the temperature. (If it is 0 degrees (F or C), then doubling or halving would still be 0, which makes no sense.)
A less scientistic but more human approach is to postulate a base temperature that most people find comfortable. Let's say it's 70F (21C, 294 Kelvin, 529 Rankine, 17 Reamur). If today is "cold", it means less than 70F. E.g., maybe today was 50F. So it was 20 degrees (F) colder than is comfortable (70 - 50 = 20). If tomorrow will be "twice as cold," it will be 70 - [2 x (70 - 50)] = 70 - (2 x 20) = 30F. Quite cold!

Well, there are a couple of ways to look at it. Does the problem specify anything else? Usually you just multiply by 2, so 0 x 2 = 0. That could be an answer. Then again, it depends on what someone means by cold. If cold is defined as anywhere below freezing (for example) then 0 is 32 degrees below freezing (assuming a fahrenheit scale) so 32 x 2 = 64 and 32 - 64 = -32. In that case -32 is the answer. It is hard to answer when you don't know what they mean.

I believe it is most logical to compare the 0 temperature of today with the temperature from yesterday then for example yesterday it was 10 degrees then there is a 10 degree drop so twice 10 is a 20 degree drop for -20....

It would be best for the truth to come out in this situation, yes. But not from you! In fact, you are the last person who should reveal this. By the way, I don't think you can hear enough times that what you did was really stupid and selfish. Especially since you knew her personally, and that she has kids. You've already done enough. I can not stress enough that you will create a huge amount of havoc and distress, and it will be worse because it came from you. Leave it. If you feel so guilty, press the husband into telling. If her husband tells her, it can be resolved quietly (at least in the view of the public and people around in), with minimal embarrassment all around, and less emotional damage for the wife. Don't bring that into the open.

0 degrees

Cold is nothing but absence of heat. Twice cold means hot by half. That much is clear, I hope. Now 0 degree Celsius is 32 degree Farenheit. Half of it will be 16 degree Farenheit. When this is converted to Celcius, it will be -8.88888 degree Celsius.

It depends on whether today is 0 degrees Celsius or 0 degrees Fahrenheit. Can you elaborate?

I think that it will still be 0 degrees, as anything multiplied by 0 equals 0. So 0x2=0.

-2, if we're talking about temperature / weather. If not, 0.
