Absolute zero can only be achieved by causing a total cessation of all molecular vibration and activity. Since this is not possible it cannot actually be attained. Temperatures close, within one degree have been achieved however.
The absolute value of any number, or y, is always positive. If y is negative, than the answer is negative y (for example, the absolute value of -3 is 3); if y is zero, it stays zero; and if it is positve, it stays positive (for example, 15 is still 15).
-459 degrees F answ2. 0 K is absolute zero, by definition under SI rules. This is equivalent to -273.15 oC. Naturally there is no SI definition for oF, but the above is equivalent to -459.67oF. Note that it is zero K, NOT zero degrees K.
