During rapid adiabatic expansion in a cloud chamber, which mechanism enhances droplet formation along ionizing particle tracks?

💡 Explanation

When a gas expands rapidly in a adiabatic process, ionization produces ions. The charged particles induce charge polarization in surrounding water molecules, leading to enhanced clustering and droplet formation along the charged particle path. Therefore, charge polarization results, rather than increased vapor pressure, reduced surface tenstion, or enhanced convection which arise from differing physical processes.
