Oceans do not dry up completely because they hold almost all the Earth's water and there would be too much to evaporate in one go. It could happen, though, in some unusual scenario - like the Earth fell towards the Sun and got very hot.

And how long does it take to evaporate that little beaker of water? Sea water does evaporate. It also gets rained on and gets rivers flowing into it and ice melting into it. Many coastal areas have salt beds where the water evaporates and leaves salt.

Because there is a balance of Co2 and limestone here. Other planets have too much of one or the other, so there is no water.

simple. Unless the earth is hollow, the water cannot drain into it - the rock/core would need to be displaced.

Because for any given temperature, water has a saturation vapor pressure. There will be no net evaporation once this saturation vapor pressure is reached.

What will happen when water boils for 2 hours.?

If you continue to boil water for 2 hours, or any extended length of time, it will evaporate, i.e. turn to steam (water vapor). Depending on how much water you have to begin with, and how long it let it boil, it could all evaporate, or only some will evaporate.


Does the thickness of the liquid affect the evaporation rate?

yes because the thicker it gets the more time it takes to evaporate.

What makes evaporation and condensation alike?

Evaporation and Condensation are based upon the energy in the water molecules. If the water temperature (vapor) is above the surface temperature, it will evaporate. If the water temperature (vapor) is below the surface temperature it will condense. Evaporation and condensation are happening at the same time. We add the term "Net" at the beginning to show which is happening at a greater rate. The temperature at which there is net condensation is referred to as dew point.


Why might you become chilled as water evaporates from your skin after you swim?

water evaporates causing a cooling effect.When the water evaporates it takes heat with it. Think of it as the water leaving and taking the heat with it.. Normal human body temperature is 98.7 (average) Your body works to heat the water in the wet clothes at the same time the outside air or ambient temperature is working to evaporate that water within the clothing. This causes a chilling or cooling effect. This is the same reason you sweat, the evaporation of the sweat acts as a cooling system.

What happens to ocean water that does not evaporate?

The water that doesn't evaporate into vapor stays in the ocean as liquid water. The oceans have a lot of liquid water. Over time, ocean water is always evaporating and turning into rain and comes back to the ocean; but the salts and minerals carried into the sea from rivers never evaporate. They stay dissolved in the ocean waters and make it saltier and saltier.


Why dosent the ocean evaporate?

Actually, it evaporates all the time. However, most of the water eventually gets back to the oceans.

What happens to water molecules when they go through the water cycle to make it back to the ocean?

water molecules just keep cycling between states. They condense, they precipitate, they evaporate. Over and over and over again. Some may make it to the ocean each time, some may not.

Does rubbing alcohol or pepsi evaporate?

At RT, rubbing alcohol would evaporate in a quicker time as its boiling point is less than that of water.
