Question

Explain the process of separation of substances with the use of more than one method with
an example. (Evaporation and Condensation)
​

Answer 1

Answer:

Evaporation: The process of conversion of water into its vapour is called evaporation.

Condensation: The process of conversation of water vapour into its liquid called condensation.

Explanation:

Evaporation and condensation are used for separating a soluble solid from water. For example; salt can be separated from a solution of salt and water; by using the combination of evaporation and condensation.

Salt is prepared from sea water by evaporation and condensation. Sea water is collected in shallow pits and allowed to evaporate. The water evaporates and crystals of salt are obtained in the pits. The salt is then sent to factories for further purification

Answer 2

Answer:

distillation and hand picking

• hand picking is the process for removing unwanted particles from grains etc
• distillation is the process to purify water and remove dust particles ect. and make water pure
