If you drink too much water, you can get water poisoning and die. And if you drink less water, you can faint or sometimes even die!
- Pure water is obtained by the process of distillation. The process of getting a pure liquid solution by evaporating it and then condensing the vapours back into the liquid is called distillation. So, when the liquid is boiled, the pure liquid turns into steam, leaving behind all contaminants present. Pure water can also be obtained from tap water by the process of distillation.
