many people say rain water is pure.but how!rain is the evapporated water from earth.isnt it so it also has sea

Question

water.can any body explains it to me plz

Answer 1

You can see how this works if you put some salt water on the stove to boil away. When the water is gone, the salt will still be in your pan. The same thing happens to everything else that isn't pure water when it evaporates.

Answer 2

There should be a slight difference between 'pure water' formed over land and sea. At sea during a violent storm, many salt-bearing droplets (in froth) go airborne and carry trace amounts of salt up into the sky. Over land, winds may carry dust aloft while moisture is evaporating. Of course sea-salt is a complex combination of chemicals unlike table salt but both salts are left in solution as water molecules leave the solution during calm evaporation. Rain drops nucleate around dust or salt particles and grow until their weight can overcome any updraft in a storm.

Answer 3

Rain can only be formed when a particulate (such as sand) reaches the upper atmosphere. The water vapor forms aound the tiny particle and then gets so heavy it falls to earth. Salt, is too heavy to evaporate and stays in the ocean. Plus, the temperature for salt to reach the state of gas is very high.

So, your question. Rain is not pure. It has a piece of dirt in it. Too tiny to see.

Answer 4

Only the water evaporates, but you're barking up the wrong tree. Rain droplets routinely form on solid particles suspended in the atmosphere, so rain water isn't pure, but it's close enough.

Answer 5

Only water evaporates. The salt and everything else in it *doesn't*. Get the idea?
