The speed of light in a vacuum is 300,000 kilometers/second. The concept of "temperature" isn't very relevant in empty space (or in nearly-empty space).When considering the speed of light in anything else than a vacuum (for example, in air, glass, or water), the material through which it travels is much more relevant than the exact temperature.
The Fahrenheit equivalent to zero degrees Centigrade is 32. Centigrade is another name for Celsius, and zero Celsius is the same as zero centigrade.
Zero degrees Centigrade is the same a 32 degrees Fahrenheit, both mark the freezing point. Therefore 0 degrees Fahrenheit would be much colder than 0 degrees Centigrade.
On the Celsius, or Centigrade temperature scale, freezing is 0 (zero) degrees. On the Celsius, or Centigrade temperature scale, freezing is 0 (zero) degrees.
Zero degrees Celsius is equal to 32 degrees Fahrenheit.
32 F
Absolute zero.
Zero degrees Kelvin is equal to -273.15 degrees Celsius.
Sub-zero is anything that is less than zero. That means that-1 degree, -2 degrees, -3 degrees, etc. are all 'sub-zero'. To be complete, you also have to specify whether you are talking centigrade or Fahrenheit. When centigrade, it just means the same as below freezing (0 degrees centigrade). When Fahrenheit, sub zero is starting to be seriously cold since freezing is +32 degrees Fahrenheit.
Zero (0) degrees, assuming you mean the freezing point of water, which is 32 degrees Fahrenheit.
No, it is zero degrees Celsius/Centigrade, which is 32 degrees Fahrenheit.
Sub-zero is anything that is less than zero. That means that-1 degree, -2 degrees, -3 degrees, etc. are all 'sub-zero'. To be complete, you also have to specify whether you are talking centigrade or Fahrenheit. When centigrade, it just means the same as below freezing (0 degrees centigrade). When Fahrenheit, sub zero is starting to be seriously cold since freezing is +32 degrees Fahrenheit.
At Zero degrees centigrade for pure water.
