How Long Does It Take For Fresh Water To Evaporate?
According to the amount of Fresh Water.
It depends is it out in the open, or in a container with a small opening? Is it moving or still water? Moving water in a 20 gallon long fish tank will evaporate around 1-2 gallons of water a week, and a 55 gallon 2-4 gallons a week.
Thank you so much. Needed it for science experiment
