If today is zero degrees and tomorow is twice as cold as today what would ?

Answer 1

Zero degrees celsius or fahrenheit or kelvin? It is nonsensical. Zero degrees is only a reference point. Temperature doesn't measure an amount. For the above poster, how cold it would be if it were three times colder then 0? 0cel=32f and -3x32 =96 so three times colder then 0 would be 96F. Doesn't make sense unless you reference to absolute zero=-273C => 0C=273K half as warm (twice as cold?) would be -176.5. Doesn't make sense. If a teacher is asking this they probably didn't do well in their univ physics classes

Answer 2

A proper answer to the assumed question requires a variable because the value "as cold" is not provided. The units of the variable are not important.

If C is the value that feels cold to you, and t is the current temperature. Then for values t < C the formula would be: t - ( C - t ) or 2t - C

Example: if 32 degrees is considered cold, twice as cold as 0 degrees is -32, or 0 - (32 - 0) = -32

Example: if 40 degrees is considered cold, twice as cold as 15 degrees is -10 degrees, or 15 - (40 - 15) = -10

Example: if 60 degrees is considered cold, twice as cold as 40 degrees is 20 degrees, or 40 - (60 - 40) = 20

Works for any kind of units assuming values do not exceed physical limitations. i.e. negative kelvin.

Answer 3

Either 459.67 Fahrenheit, 273.15 Celsius, 0 Kelvin or 0 Rankine.

There's a problem in answering your question in that you can't multiply temperatures and that's because the two most commonly used measurements (Fahrenheit and Celsius / Centigrade) aren't relative - 0 isn't the lowest you can get.

Unless... you're talking about the Kelvin or Rankine scales which take the coldest possible temperature as being 0. This is 273.15 degrees Celsius below freezing and is called Absolute Zero, it's the temperature at which everything freezes.

Using the Kelvin scale temperatures can be multiplied and if today's temperature was 0 Kelvin then tomorrow's would also be 0 Kelvin (0 x 2 = 0).

If it was 0 Celsius today we could convert that to Kelvin (273.15K) then multiply by 2 which would mean the temperature tomorrow would be 273.15 Celsius. Converting 0 Fahrenheit to Kelvin, multiplying by 2 and converting back to Fahrenheit would give a temperature for tomorrow of 459.67 F.

Let's hope that tomorrow isn't twice as cold (or hot) as today.

Answer 4

Assuming you're working in Fahrenheit, zero degrees F is equal to negative 18 degrees Celsius. so -18 x 2 = -36. -36c= -33f

soooo if it is zero today and will be twice as cold tomorrow it will be -33f

Answer 5

Let's say today is 0 Celsius = 32 F
If tomorrow it's twice as cold as today it would be
32F x (-2)
= - 32 F

Answer 6

Zero degrees Fahrenheit is 32 degrees below freezing, so double that.-32 degrees

Answer 7

Convert to Kelvin (273, assuming we're talking about the freezing point of water), then divide by 2.

Answer 8

Impossible to answer given the parameters. We need to know what scale you are using and scale is realative to the user.
So the answer is 2X0F= 0
or
2X0C= 0

Answer 9
