A - there are more water molecules than salt molecules in the ocean.
B - only water vapor molecules, and not salt molecules, evaporate.
C - the salt dissolves and forms a solution, which becomes more and more dilute untill all the water is fresh.

Think about the question for a second before posting.

Can salt evaporate? - No.

Therefore, the answer is B.

Well to start with, salt molecules are bigger and denser (aka heavier) than water molecules. The answer to your question would theoretically be B.

In some cases what water treatment plants do to get the salt out of the water is they'll heat up the water to extreme temperatures so that the water evaporates into water vapor and the salt will stay at the bottom in solid form while the water is carried away from the tank.

And in reverse osmosis what they'll do is they'll have a very fine filter blocking 2 seperate tanks with holes big enough for water molecules to penetrate but not for salt molecules. When pressure is applied to the salt-water tank the water goes through the filter. After the process a gooey and very salty paste is left over and put back into the ocean. This is primarily how arid areas such as the Middle East get their water supply. It is also why major cities there are mostly located on the ocean or a large bay instead of inland. But of course water is piped through the region for the remote villages and small towns that are found inland.

B is most nearly correct, however its phraseology is wrong because the molecules don't evaporate.

In the sea the salt molecules and water molecules are simply a solution, along with a lot of other substances. They never really join together to any extent. They just form a solution like unset jello or brewed coffee.

Salt doesn't evaporate, but it can go into the air. It's heavier, so the water vapor will rise higher and eventually separate entirely from the salt.

If you live near an ocean the salt in the air will cause corrosion, however that salt isn't necessarily part of water vapor. The salt will tend to settle either on land or back in the ocean.

Water can exist in three states, as do the majority of other elements or compounds. It can be liquid--water, solid--ice, or gaseous--steam or water vapor.

which can prove to be very helpfull if you were standed on an island with no fresh water.... if you were to fill a small hole in the ground with salt water, and used some type of tarp or thick canvas pulled tightly over the water hole, the dew that condensed would be pure to drink

B. The salt stays in the ocean.

The answer is B. Good way to do your homework.

Only the water evaporates. When controlled, the process of purifying fluid by evaporation is distillation.

b.duh! Salt is too heavy to evaporate.
