Solution Droplets

  • Note that the previous discussion is valid for a pure water drop

  • if a droplet is comprised of a solution - it can be in equilibrium with the environment at a much lower RH -->

  • this explains the formation of haze

  • This process of condensation will grow drops , but not to precipitation sizes š 2 mm

  • Q: So, if a droplet grows to some size by condensation, how can it continue to grow to precipitation size???


Haze particles can form when the relative humidity is less than 100%. Are these haze particles pure water droplets or solution droplets? Why?
