You keep talking "water" but WATER IS A CHEMICAL. H20 What the heck do you need water droplets for? 2 Parts Hydrogen, 1 Part Oxygen = Water.
Do you think 1 molecule of H20 is enough to form a cloud, or even a drop of water???? hahahaha
How many molecules in a drop of water?
I'm sure that doesn't help with
How big is a drop? "A drop" is not a precise measurement. It depends on a number of factors. If you measure how big the drops of water are
you're talking about, (in millilitre) then you could figure out the number of molecules based on the fact that Avogadro's number of water molecules
have a volume of about 18 milliliters. Avogadro's number is 6.022 * 1023 (particles) per mole One drop:average volume about 0.05 ml = 0.05 g Molar
mass of water 18.01 g/mol Meaning: about 1.7*1021 molecules in a drop of water: don't start counting them!
I've used both H2
O and "water" interchangeably in this thread, so don't go making it sound like I have no idea what
HOWEVER, I'm not going to use "hydrogen and oxygen" interchangeably with "H2
O" or "water", because when most people speak of hydrogen
and oxygen in the atmosphere, it is usually about free molecules of hydrogen and oxygen -- NOT water (one of the chemically bonded forms of hydrogen
In fact, elemental hydrogen (hydrogen by itself) makes up a very
tiny portion of the atmosphere. A very, very tiny part.
That's why I have no idea why you insisted on telling us that clouds were molecules of hydrogen and oxygen, rather than saying they were molecules of
O (water). Water is very different that its two component elements.
It is MUCH more accurate to say a cloud is made of molecules of liquid water droplets or frozen water crystals than to say it is made of hydrogen and
oxygen molecules. While water is technically hydrogen and oxygen, the stuff in clouds is water, and behaves as water, NOT as elemental hydrogen and
As for the rest of your post quoted above, that's a fun fact, but why are you telling us this? And why on Earth would you believe that I think one
water molecule is enough to make a cloud or a drop (whatever the vague definition of a "drop" is size-wise). Do you think I'm 6 years old?
Plus, you do realize that you are making my argument for me (and ruining yours). For water to be visible (such as in a cloud) it needs to have a
certain density. That density of molecules in a visible cloud facilitates the nucleating of the water droplets onto the cloud seeding "seeds" of
silver iodide (or salt). In the case of regular clear air, the H2
O molecules are much more sparse, because they are in their gaseous
form rather than their form in clouds -- where H2
O is either in its liquid or frozen form. In this sparse gaseous for, the nucleating
required for cloud seeding cannot take place.
