<s>[INST] A cesium atomic clock uses a 9.192631770 × 10^9 Hz signal. This frequency can also be expressed with respect to a cesium atom in its natural frequency. Given that the Boltzmann constant is 1.3806504 × 10^-23 J / K, calculate the temperature (T) that will cause the cesium atom to resonate at the signal frequency if the cesium atom can be treated as being in a two-level system.[/INST]
