As-Salafee Posted August 12, 2005 Share Posted August 12, 2005 Hello everyone, I would like to know something about rain, mist, clouds etc. Does rain distill from mist? Suppose you have evaporation, does that water distill from a mist as rain? As you can see, fog is just like rain, ie, the air has become 100% saturated and condenses into water droplets. Can you authenticate this quote for me? Thank you. Link to comment Share on other sites More sharing options...
Sophist Posted August 12, 2005 Share Posted August 12, 2005 Rain is water, which has condensed around nuclei and accumulated to form large droplets. Clouds stay in the air because when the water condenses, latent heat is released which maintains the cloud in the atmosphere. Mist on the other hand, is a low-lying cloud made of much finer droplets. If the air is sufficiently saturated and there are sufficient nuclei present then the water may condense into a mist of fog. This happens when due point temperature is reached; ie: the temperature at which atmospheric moisture in the form of gas condenses to liquid. A fog and mist are quite similar. They develop when the ground (which is cooler than the air) causes the air to cool and the water to condense. Alternatively, a warm and cold body of air may meet, which will cause some of the warm air to cool and again, the gaseous moisture will condense. " Mist is a visibility between 1000 and 2000 metres. Normally, over land, forecasters use the word "fog" when the visibility is 200 metres or less." Link to comment Share on other sites More sharing options...
As-Salafee Posted August 13, 2005 Author Share Posted August 13, 2005 Would it be safe to say that water distills from mist in the mode of rain? Or is it just water droplets floating around? Link to comment Share on other sites More sharing options...

I'm not sure why you're using the word distills. It doesn't really have any meaning in this context. Distillation is a means of separating liquids through differences in their vapor pressures. *Wikipedia* Are you trying to ask if rain forms from mist? Like mist is water... Like sophist said mist is just suspended water droplets that form around nuclei. Much smaller when they're close to the ground as fog. Or in clounds when they get heavy enough they fall to the ground as rain, or snow... Link to comment Share on other sites More sharing options...
