Liquid water molecules are transformed in a gas.
Transpiration, Precipitation, Groundwater.
evaporation gives the atoms more energy
These are molecules of a gaseous phase.
Dissolution and evaporation are physical processes but they are not similar.
When you heat water, like anything else, its temperature or energy increases. The molecules will have more and more motion, i.e. more and more energy - this is the definition of temperature. At the boiling point of water, which varies depending on pressure, if you continue to heat it the molecules will start to disassociate and they will become gaseous.
Those ones that are most like water. Like dissolves like.
They just aren't there. The water molecules are somewhere else. It's less chemistry than a more macro-scale science like Meteorology.
Which of the following statements about evaporation are true? Select all that apply. Evaporation only occurs over oceans. Water only evaporates when it boils. Heat from the sun can power evaporation. Evaporation from plant leaves is called transpiration.

yes, evaporation raises salinity because salt doesnt evaporate like water

They can't because evaporation occurs over the oceans. Evaporation is the process by which liquid water is converted into a gaseous form of water. Because the salt in the ocean is made of minerals it does not evaporate with the water, which means that during evaporation only the water is evaporated leaving behind the minerals. This may seem like it would be only a big body of salt eventually, but during the water cycle, the water is precipitated back into the ground and other bodies of water. This means that in conclusion due to the water cycle the oceans cannot be over salted.
No the substances like molecules donot chane during physical change .
Usually evaporation, but keep in mind that when water freezes (like the polar ice areas) the water molecules tend to crystallize with only water molecules, which pushes other stuff like salt out, resulting in higher salinity in the water that is left.

It seems like there may be a spelling error in your question. Do you mean "evaporation"? Evaporation is the process in which a liquid, such as water, transforms into a gas, usually due to exposure to heat or dry air. This occurs when the molecules in the liquid gain enough energy to break free of the surface and turn into vapor.

A thin layer of oil on top of water will mostly prevent the water from evaporating, because the oil will float on top of the water and keep the water molecules from escaping from the water's surface. Water dissolves very little in ordinary oil, so hardly any water molecules diffuse through the oil.Some oils evaporate themselves, though, and if you wait long enough, the oil may evaporate away, leaving a hole for the water underneath to evaporate. If the oil layer is too thin, it may leave a hole somewhere for the water molecules to escape by evaporation. Emulsifying agents, like soap, stick to oil molecules and to water molecules, allowing the two to mix. Adding soap to water with oil on top of it may allow the water to evaporate.Really dirty oil, like the stuff you get out of car engines if the oil isn't changed often enough, may contain so many small metal particles in it that it will sink in water. This kind of oil will just sit on the bottom and not affect the evaporation rate.Answer by MfAnswers
through a process known as evaporation which is when the water gets to a certant heat it turns into tiny particals and goes in the air like steam.
