    b/c .... because?
    Who knows? Megabrain said it best.

    Now, we do not see a cloud because it contains ice crystals. We see it because it contains condensed water droplets. Incidentally, it may also contain ice crystals.

    Clouds do not form because the temperature is at or below zero degrees Celsius (note the spelling, please). Clouds form when the humidity rises to 100% and there are nuclei - such as dust particles - to act as seeds for the condensing water droplets.

    I still don't know what you were asking, but these brief notes may have shed soem light on your interest. If not do ask again, but try to make your intention clearer.

    Regards
    O
