A volume of air has a temperature of 0 C. An equal volume of air that is twice as hot has a temperature of
0 C.
2 C.
100 C.
273 C.
none of these

Since 0 degrees Celsius equals 273 degrees Kelvin, then air that is twice as hot would be equal to 546 degrees Kelvin, which when converted back to Celsius is equal to 273 degrees Celsius.
The natural urge is to double the Celsius temperature, [ let's say it was 5 degrees Celsius, then you'd probably want to double it to 10 degrees Celsius, however, that isn't correct. True temperature is

measured in Kelvins, so you must convert to Kelvin to find out the true temperature conversion.
Hope this answers the question.

Weegy: The answer is a. 0 degrees C.
The lowest POSSIBLE temperature in nature is absolute zero, which defines 0 degrees Kelvin (-273.15 degrees C. [ [ or -459.67 degrees F.) If by 'nature' you mean ANYWHERE outside a laboratory, intergalactic space would probably offer the lowest temperatures in the known Universe.
Temperature measures the average kinetic energy of any object's molecules or atoms. Since by definition it contains no ... (More)
