How do you separate sea water from pure water?
evaporate the water or evaporation. condense the water vapour or condensation
Which of the processes associated with the water cycle might be responsible for helping to clean or filter the water?
When evaporation occurs, all impurities leave the water. However, for condensation to happen, water has to form around a particle. Distilled water is pure from evaporation and forced condensation.
How can you recover crystallized pure iodine which is dissolved in water?
A method is the evaporation of the solution.
Distillation?
The process of evaporation(boiling) and condensation at the same time (simultaneously) to get pure liquid from a solution is known as Distillation.
What is a suitable method for separating salt from seawater?
Allow the water to evaporate, leaving behind the salt would be effective for separating salt and water in a mixture.
How will you prepare crystals of pure common salt from sea water?
We can use evaporation method. water will evaporate from saline water on heating and salt is left behind.
Distillation is the method used to seperate what?
A liquid from a solid (evaporation of water to create pure water), One liquid from another (alcohol in wine from the water to make spirits).
How do you get water out of sea water?
Evaporation and condensation, first the water has to evaporate from the rag or thing thats holding the seawater. Then it has to condense on a usually plastic or seethrough surface hanging over the seawater. (the water needs the sun's heat to evaporate the water) it codenses and then the water is pure H20
Why is distillation used in chemistry?
>to get a pure sustance (such as water from sea water) >to separate alcohol from water to make distilled spirits such as vodka, >to extract essential oils from plants >to divide crude oil into all of its different components (paraffin, tar, and all of the other substances used as fuel that are extracted)
Which methods can be used to obtain fresh water from seawater?
The process of converting salt water to fresh water is called desalination and there is a lot of information on the subject. Mother nature turns salt water into fresh water everyday by evaporation of water from the oceans. Clouds, with water vapor, water droplets and ice crystals form from evaporation. Then, it rains or snows nearly pure water/ice. When humans artificially create pure water, the water is typically heated to drive the pure water off as water vapor and leave the salts behind. In chemistry, heating a liquid to vaporize it so that it condenses in a purer form is a process is called "distillation". Another process, more specifically for water, is reverse osmosis filtration through a series of differentially permeable membranes allowing pure water to pass while trapping salts and other impurities. When any process is used to remove salts from seawater, the process is called desalination.
Why does the evaporation increase the density if ocean water?
By evaporation concentration of salt increase; salted water has a higher density than pure water.
How is evaporation and condensation used in industries?
The solvent, usually water, is boiled off by the addition of heat energy, often under reduced pressure Condensation is the opposite of evaporation and has the same temperature as the BP of the liquid. When heat energy is removed from a gas or vapour, it begins to condense
