Distillation.
The true statement about distillation is that it may leave some chemicals such as herbicides and pesticides in the water.
Distillation is a process of separating substances from a liquid mixture by evaporation and condensation. It involves heating the mixture to vaporize the volatile components and then condensing the vapor to obtain pure liquid.
To determine the answer to this question, you can eliminate the other options by using the process of elimination.
The first option states that distillation uses semipermeable membranes to filter out particles. However, this is incorrect. Distillation does not involve the use of semipermeable membranes for filtration.
The second option mentions that distillation removes mainly large particulate contaminants which settle to the bottom. This is also incorrect. Distillation is primarily used for separating liquids based on their boiling points and does not target particulate contaminants.
The third option claims that distillation is one of the easiest and cheapest filtration solutions to implement. However, this is not accurate either. While distillation is effective for purifying water, it can be energy-intensive and expensive to implement on a large scale.
Therefore, the only remaining option is that distillation may leave some chemicals such as herbicides and pesticides in the water. Distillation is not guaranteed to remove all types of chemicals, especially those with lower boiling points than water.
