Question

Sea water can be purified by the process of (a) distillation (b) evaporation (c) filtration (d) fractional distillation

Answer 1

Hope that distillation will the answer

Answer 2

Seawater can be purified by the process of distillation. (Option a)

• In this process, the liquid that needs purification is heated up till it vapourises and is then condensed back to its liquid form.
• The seawater is heated up which kills the pollutants and is condensed back to get pure water.
• Filtration does not separate salt from the water and doesn't work.
• Evaporation does not make it suitable for consumption and Fraction distillation is used to separate various components.
