Clouds are colloids. what are the dispersed particles

Water droplets slowly forming until they reach a size that can no longer be suspended in the air.  

Explanation:

When air becomes saturated with whater, it can no longer maintain water as a gas.  Some water molecule come together and stay that way.  They, in turn, coallesce with other nearby particles.  This continues until the droplets are large enough that they begin to noticeably refract the sunlight, producting the visual effect we call clouds.  The droplets are suspended in air - an heterogenous suspension called a colloid.  At some point the colloid cloud begins to shed the larger water droplets, usually directly over my spot on the trail.

explanation:

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
