Answer 1

Answer:

2 Boiling is a correct answer

Answer 2

Answer:

2) boiling

The simplest method to purify water is to boil it for a good amount of time. High temperatures cause the bacteria and virus to dissipate, removing all impurities from the water. In doing so, chemical additions cease to exist in the water as well. However, the dead micro-organisms and impurities settle at the bottom of the water, and boiling does not help eliminate all the impurities. You must strain the water through a microporous sieve to completely get rid of the impurities.
