• Compared simulation results with existing theoretical models.
• Developed a new theoretical model to explain observed temperature dependencies.
• Confirmed theoretical models for hard-sphere gas collision densities.
• Identified temperature dependence in the ratio of ternary to binary collisions in Lennard-Jones gas.
• Proposed a new model explaining the temperature effects on collision density.
