Evaporated water can be made pure under controlled conditions, but in nature it is frequently impure. When water evaporates, it does leave behind any solid contaminants such as metals and salts, so it gets purified to that extent. But evaporated water can contain some liquid and gaseous contaminants that make it impure. Perhaps you have heard of "acid rain", which is evaporated water contaminated with carbon dioxide, sulfur oxides, nitrogen oxides, and hydrogen chloride gases. Evaporated water can also be contaminated with some volatile water-soluble organic compounds.

∙ 15y agono. simply because there are less "obstructions" inside the water for water molecules to bounce off of and increase the kenetic energy quicker. In the long run, it takes longer for water molecules themselves to get excited enough to evaporate than water with imputities.

∙ 6y agoDuring the process of evaporation, impurities in the water are left behind. As a result, the water that goes into the atmosphere is cleaner than it was on Earth

∙ 13y agoWhen water is evaporated, any solids that are present in the water are left behind as they don't evaporate. this means that the water is cleaner.

∙ 14y agodepends where u get it from out of a river yes out of taps no because it has had stuf put in it 2 make it disease free and clean

∙ 12y agoYes,of course it is!It leaves behind salt minerals and other stuff and only water will evaporate.

Are variables in evaporation?
For evaporation from a pure water surface, the rate of evaporation is proportional to the difference in vapor pressure between that of the water surface and that of the bulk air over it. The vapor pressure of water in turn depends on its temperature.
Which water evaporate fast salt water or pure water?
pure waterDiscussionDissolving something in water which does not evaporate easily will make the mixed solution less likely to evaporate than pure water. The more stuff you add to it, the less likely it will evaporate.Adding salt to water makes ions in solution and these ions reduce the vapor pressure of the solution compared to pure water. The lower the vapor pressure of a liquid or solution, the slower it will evaporate. This effect is also related to boiling point elevation and freezing point depression.
Which fuel produces only water as a waste product?
When hydrogen is burned the product is pure water vapor. Here is the equation: 2H2 + O2 = 2H2O
What form of water is the most abundant at any time in the water cycle?
water vapor
What happen to the water in each process in water cycle?
(evaporation) water becomes vapor, (condensation)vapor is still vapor, (precipitation) vapor becomes water again...
Is water vapor pure substance or mixture?
Water vapor is a pure substance.
Is water vapor a mixture or pure substance?
Water vapor is a gas, not a mixture. Water vapor is just the gas form of water, it is not a mixture.Water Vapor is a compound made by bonding Hydrogen and Oxygen.
A pure solvent has a vapor pressure the vapor pressure of a solution A.EQUALTO B.LOWER THAN C.higher than?
A solution has a higher vapor pressure than a pure solvent. This is why salt water boils faster than pure water.
What is vapor pressure of water?
The vapor pressure of pure water at 25 degrees Celsius is 23.8 torr.
The presence of water vapor in pure air?
Increases Density
How much water will a car that burns hydrogen exhaust?
if it runs on pure hydrogen then the only exhaust will be pure water vapor.
How will the vapor pressure of pure water compare to an aqueous solution of sodium chloride?
The solution's vapor pressure will be lower.
Is water vapour a mixture element or a compound?
Pure water vapor is a compound, just as liquid water is.
Is rainwater is pure form of water or distillted water?
It is based as salt water but then turned into pure water. 1. The ocean water evaporates into water vapor leaving all the salt and other chemicals behind 2.The water vapor turns into clouds 3.The clouds build up in water so much they rain. So yes rain water is pure
How do you turn salt water to pure water?
Distillation is the easiest way. Heat the water until it evaporates, leaving the salt behind. Catch and condense the water vapor into pure water.
Is water vapor an element a compound or a mixture?
Pure water vapor is a compound, just as liquid water is.
How could a sample of pure water be obtained from the drink?
You could distill the water from the lemon drink and condense the water vapor and collect the water in a container.
