What water takes the longest to evaporate dirty water soapy water or regular water?

Answer 1

The answer would depend on the ability of the water molecules to escape into the surrounding atmosphere. So what would help them escape? Dirty water would warm up in the sun faster, so you'd have a higher temperature and faster evaporation. The soapy water would bring oil to the surface and hinder the escape of the water molecules. So the order of which takes the longest would be: 1) soapy water, 2)regular water, 3)dirty water.

Answer 2

Dirty water and soapy water would generally take longer to evaporate than regular water because the impurities in the water (like dirt or soap particles) can hinder the evaporation process by increasing the liquid's surface tension. This creates a barrier that slows down the escape of water molecules into the air.
