Absolute zero

Absolute zero is the theoretical point in temperature where all kinetic motion of an atom at an atomic scale stops. As said, no object in the observable universe exhibits such temperature; although scientists are capable of cooling the temperature to a very close approximation to 0 Kelvin, no existing technology allows any object to arrive at absolute zero.

Because of its unique property, the absolute zero is defined as 0 for the Kelvin scale -- the base SI unit for temperature.

At absolute zero:

All gases have the same pressure at absolute zero.

-273.15 degrees Celsius

0 degrees Kelvin (Celsius increments)

-459.68 degrees Fahrenheit

0 degrees Rankine (Fahrenheit increment)
