because it blocks water from evaporating
yes it does. The evaporation rate of water is dependent on the number of molecules that can be presented to the evaporating surface. Anything in the water besides water will decrease this density and slow the process of evaporation.
A lot of things get wet, in the rain, and they all are sources of evaporating water, so the rate of evaporation temporarily increases. Eventually things dry out and return to normal.
Maybe your water is evaporating off. If you put glass covers on your tank you will cut down the evaporation rate considerably.
Yes it does!
A change in medium water to Gelatin would affect the rate of diffusion dramatically. The change from water to gelatin would slow down the rate of diffusion.
yess it will soke it up (someone else posted this) This answer does not say which additive will slow the evaporation of water, which is what I want to know. I live at 6000' in a semi-arid climate and would like to know if there is an additive that will slow the rate of evaporation of water. Up here evaporation is rapid. Thanks.
Liquids beacomes vapor when you apply heat to them. However, the point when a certain liquid becomes vapor or rich their point of evaporation still depends on their evaporating rate. Liquids differs in their evaporaing rate, for example oil has different evaporating period to water. We all know that water evaporates at 100 degree celcius but other liquids evaporates at different point, it could be higher or lower than the water.
A decrease of temperature involve a decrease of the evaporation rate.
Yes, that is partially true. While water is being heated, once its temperature reaches boiling, the water will remain at boiling until all of the water boils away. So, Yes, it does turn to gas, but, No, it doesn't turn to gas all at once. Prior to reaching boiling, the water would have been evaporating at a slower rate. The only thing magical about the boiling point is that is the temperature where the pressure of the evaporating water equals atmospheric pressure.
diluting with water
Cold water simply slows down the rate at which salt dissolves.
