b Explaining how pure water is obtained from sea water by distillation
Sea water contains a high concentration of salts and other impurities, making it unsuitable for direct consumption. To obtain pure water from sea water, the process of distillation is often used.
Distillation process
- In distillation, sea water is heated to its boiling point, causing the water to evaporate and leave behind the salts and impurities.
- The water vapor is then collected and condensed back into liquid form, resulting in pure water that is free from impurities.
Advantages of distillation
- Distillation is a reliable method for obtaining pure water from sea water.
- It is a simple and effective process that can be scaled up for large-scale water purification.
Disadvantages of distillation
- Distillation requires a significant amount of energy to heat the sea water to its boiling point, making it somewhat energy-intensive.
- The process can be slow compared to other water purification methods.
Conclusion
In conclusion, distillation is a commonly used method for obtaining pure water from sea water. While it has its disadvantages, its reliability and effectiveness make it a popular choice for water purification, especially in areas where access to clean water is limited.
