The temperature of the air at absolute zero is 0 Kelvin (K), which is equivalent to -273.15 degrees Celsius (°C) or -459.67 degrees Fahrenheit (°F).

Here's why:

* Absolute zero is the theoretical point at which all molecular motion ceases. This means that atoms and molecules have no kinetic energy.

* Temperature is a measure of the average kinetic energy of the particles in a substance.

* Therefore, at absolute zero, the temperature of any substance, including air, would be 0 Kelvin.

It's important to note that:

* Reaching absolute zero is impossible in practice. While scientists have been able to achieve temperatures extremely close to absolute zero, it's impossible to reach it completely due to the laws of thermodynamics.

* Air itself wouldn't exist as a gas at absolute zero. At such a low temperature, the air molecules would condense into a solid state.
