Suggest two method to purify water for drinking purpose with explantation​

Answer 1

Answer:

Heating and filtration are the best ways to purify water for drinking.

Heating: To purify water we have to heat the water until 100°C . Because purify water means without any bacteria. So, to kill bacteria we heat the water at 100°C .

But it is not possible to heat water at 100°C because if we heat at this C ,the water converts to evaporation. That's why , to drink water at home we have to heat the water at 20° to 40° C .

Filtration: It is a process by which we generally purify water at home .

To filtrate water we need small rocks, sand , Charcoal, a three containers and a piece of cloth......the diagram is given above .
