You can slow down the rate of evaporation by reducing exposure to heat and wind, covering the surface with a lid or cloth, or reducing the surface area of the liquid. Additionally, adding a layer of oil can also help prevent evaporation.
cool it down
A decrease of temperature involve a decrease of the evaporation rate.
Yes. Evaporation will cause temperature to decrease or will slow down a temperature increase.
stop
Salt will slow freezing, but not evaporation. As say salt water evaporates, it will leave behind its salt contents, but it will not evaporate any slower than fresh water.
plants?
The evaporation of water is slow when water is dissolved in salt. This is because of the salt molecules, the salt molecules is the reason for the slow evaporation.
Wind resistance.
Wrap it in paper or something this will slow down the evaporation.
Plant trees between fields to slow wind erosionStrip FarmingContour Plowing
Evaporation is very slow at converting liquid to gas compared to boiling.
