name Debbie status other grade other location CT Question - My third grader was doing an experiment to see if salt or plain water would evaporate first. We did much research (including your web site) and expected to confirm that the plain water would evaporate first (or that the difference would be undetectable).

Water is transferred from the surface to the atmosphere through evaporation, the process by which water changes from a liquid to a gas. ... Most evaporated water exists as a gas outside of clouds and evaporation is more intense in the presence of warmer temperatures. This is shown in the image above,

I conducted the experiment 3 times, and I found out that the solution with 0% salt had a faster evaporation rate than those of 5%, 10% and 15% (all were with 500 mL of water). I have been searching and thinking of reasons why this is so, but I have been unlucky in finding the answer.

Re: Does the amount of salt in a water solution affect evaporation rates? Date: Mon Mar 23 13:58:11 1998; Posted By: John Letourneau, Lab Technician, ... Another experiment that demonstrates this phenomenon is the temperature at which water boils when it is salted as opposed to when it is not salted. Good Luck!!
