Ar2 dimer can be considered as a diatomic molecule, which consists of two argon atoms connected by intermolecular bonds. When such a gas is heated from temperature T0 to temperature T = 4T0, the dimer disintegrates into atoms. The collision cross section for atoms is k = 1.6 times smaller than the collision cross section for Ar2 molecules. How many times did the thermal conductivity of the gas change as a result of heating?
