maybe it is the practical way because it is the simplest way of purifying liquids --------------------- Technically simple, maybe, but practical? Not really. Distillation is extremely energy intensive when done on a large scale because of the high boiling point of water. A medium-population city (~2 million people) uses around 1300 ML of water a day. It takes 4.184 kJ to raise the temperature of 1 kg of water by 1 K. To boil all 1300 ML of water (1300000000 kg) from 25 degrees to 100 degrees just once would need about 407.9 TJ of energy. Factoring in the inefficiencies of the machinary, the energy requirement can go up to 1 PJ, or about 277000000 kW.h or 277 GW.h. Even the largest power plant in the world, the Three Gorges dam, only produces an average of about 221 GW.h per day. Also, 277 GW.h of energy would cost about 19 million dollars at current energy prices. Such astronomical amounts of energy and money required to supply even a medium-sized city precludes the possibility of using distillation as a practical means of purifying water. This is precisely the reason why the world is fighting over fresh water resources, since if distillation can be economically applied to salt water in the ocean to purify it, there will never be any water shortage.
What else can I help you with?
In distillation a liquid and then condenses?
correct! distillation is the prosses of evaporating a liquid to purify it then recondence it back to a liquid. This prosses can be used for removing salt from water.
How long does it take to purify water?
It takes a while to purify water
Why is distillation expensive?
Distillation isn't expensive. Distilled spirits are expensive because of the taxes levied on them by governments.
How do you separate water from alcohol?
You can separate water from alcohol by fractional distillation. By heating the mixture to the right temperature, the alcohol will evaporate and leave the water behind. However, alcohols and water are quite difficult to separate completely, and the separation will not be 100% by this method.
What is it called when you remove salt from water by heating the water until it vaporizes and leaves the salt behind?
chilling or refrigeration =========================
What is the process used to purify water?
distillation
How do you purify water by heating and evaporating?
You think probable to water distillation.
Is distillation a practical way to purify water for a small laboratory?
Yes, distillation is a practical method to purify water in a small laboratory as it effectively removes most impurities, including contaminants and pathogens. However, it can be time-consuming and energy-intensive compared to other methods like filtration or reverse osmosis. It is important to consider the specific needs and resources of the laboratory before choosing a water purification method.
What are the advantages of evaporation over distillation?
With evaporation you can't purify water.
Are there other options to purify water other than using a filter?
One way to purify water without a filter is distillation. In distillation, water is boiled, and then the water vapor is cooled and it condenses as pure water. However, this can be more expensive than filtering water.
In distillation a liquid and then condenses?
correct! distillation is the prosses of evaporating a liquid to purify it then recondence it back to a liquid. This prosses can be used for removing salt from water.
What is one way you can purify water?
Boiling water is an effective way to purify it. Bringing water to a rolling boil for at least one minute will kill most germs and pathogens, making it safe to drink.
Is it possible to purify water using distillation and filtration methods?
Yes. This is how water is purified to get distilled water and/or deionized water.
Which physical method commonly used to purify sea water is?
Desalination is a common physical method used to purify sea water. It involves removing salts and minerals from sea water to make it suitable for drinking or other uses. Techniques such as reverse osmosis and distillation are commonly used in desalination plants.
How is distillation related to the water cycle?
Distillation is a process that mimics part of the water cycle by separating water from impurities through evaporation and condensation. In nature, water evaporates from bodies of water, condenses in the atmosphere to form clouds, and then falls back to Earth as precipitation. Distillation uses the same principles to purify water by evaporating it to separate from contaminants and then condensing it back into liquid form.
Why is distillation so important in hot countries?
Distillation is important in hot countries because it is an effective way to purify water by removing impurities and contaminants, making it safe to drink. In hot climates, there is a higher risk of waterborne diseases due to increased bacterial growth, so using distillation helps ensure access to clean and safe drinking water. Additionally, distillation can also be used to produce essential oils and spirits, which can have various practical and economic benefits in hot regions.
