Question

Celina has a water sample that’s contaminated with salt and microorganisms. Which method should she use to purify the water?

Answer 1

Answer: evaporation

Step-by-step explanation:

The boiling of water till it evaporate allow the salt to remain in the pan and the high temperature kills the microorganisms

She should collect the vapor with a cooking pipe in another container

Answer 2

Celina should perform the following method to get pure water:

Boil the water in a pan, as the water boils it changes into gas (water vapours) these vapours should be cooled down through the process of condensation which changes gas into liquid form, Through this process germs would be killed due to high temperature and the salt will remain in the pan as salt has higher boiling point than water,
