Fractional Evaporation is done in a long tube the item to be evaporated is heated in the bottom and then the vapors are allowed to rise as the item (suppose crude oil) is made up of diffrent liquid all the liquid will have diffrent condensation point also so will condense at different height and the tray put at these heights will collect the different items at different altitude.

You can observe this yourself by breathing on a mirror. As the condensation evaporates from the mirror, you have completed the water cycle. Water evaporates into the atmosphere from the ocean, lakes, rivers, and from soil and plants, and even from your skin and breath. When the air reaches saturation (100% humidity) due to cooling or changes in atmospheric pressure (or both) the water condenses from vapor to liquid (or solid) and falls to earth as rain, snow, sleet, hail, or maybe only as dew. This water may then form streams and rivers and return to the ocean where it may evaporate again into the atmosphere or it may sink into the earth where it becomes groundwater that may take many thousands of years to emerge again, or may be pumped to the surface from a well and used for drinking water or irrigation. It is a continuous cycle that may take only seconds or may take thousands of years to complete the cycle depending on the path of the water.

Evaporation is the process whereby atoms or molecules in a liquid state (or solid state if the substance sublimes) gain sufficient energy to enter the gaseous state. \n\nOR\nEvaporation : \nThe conversion of a liquid (eg water) into a vapor (a gaseous state) usually through the application of heat energy; the opposite of condensation.  \n\n\nExpansion : the act of increasing (something) in size or volume or quantity or scope

Evaporation- liquid changes to a gas\nCondensation- gas changes to a liquid

Are you talking molecular level or physical process?\n\nWater is the bond between Hydrogen+ and two Oxygen- formulating H2O.\n\nWater as in the rain.  Evaporation is the water droplets from the sun heating up the water rising to the sky, also the plants perspire its water from the heating of the sun and rises to the sky, then condensation is the cooling of the droplets and condensing, weighs down the cloud with concentrated & heavier droplets and precipitation is the actually rain droplets falling to Earth.\n\nThe chemical process of cleaning the water to drink is the earthly cycle, but you want to go with human cleaning is the introduction of a sanitizing and killing bacteria in the water with chlorine and making it supposedly healthy with fluoride.  And a bunch of supposed microfilters to catch debris and bacteria.  Heating the water also helps clean it a little.

condensation is the liquifcation of moisture in the air from a gas to a solid. vapor turning in to water for example.

Distillation... if the liquids have boiling points within 100 degrees celsius, then fractional distillation should be used.  Otherwise, simple distillation is a lot easier.

Condensation - the warm moist air in the car cools down and when it 'hits' the glass colled by the outside air and leaves a film, then drops of water.

These are physical changes.  The matter simple changes state, depending on tempature.  Also see evaporation.

Water that is evaporating is not the same as water boiling. evaporation is the loss water from the surface that is still water in very small amounts that become suspended in the air. Boiling that occurs at 100c is a state change in the water where the bonds in the water lattice have been broken. The steam then coming in contact with the cooler surrounding air then rapidly cools and forms water droplets on cooler surfaces or in the air and just like fog is a saturation of the air with water and you can see it so you also can see the steam re condensing into water in the air.

Evaporation.\n\nSalt water + heat source + vessel. Apply heat source to vessel containing salt water. Evaporate water. Harvest salt.

condensation--the difference in temperature from the outside and the water in the glass causes the water to condense and it gets wet.

its called phase change of water, but it is given a common name known as evaporation

fractional uncertainty, or deltaV/V is 1% or 0.01.\n\nto obtain uncertainty deltaV, just multiply 1.5E3 by 0.01. then multiply by 1billion or 1E9 to obtain answer in nm.
