Pure water evaporates faster. This is because the presence of impurities (salt) in the water causes the boiling point of the water to increase.
The greater the difference between the boiling point of a substance and room temperature, the longer it takes for that substance to evaporate. So, pure water takes less time to evaporate.
Of course, other conditions such as temperature, surface area to atmosphere, relative humidity and atmospheric pressure should be constant for both so as to investigate only the effect of salt on the evaporation of water.
The sugar water would evaporate faster than the salt because sugar dissolves in the water making it stay thin, while the salt makes water thicker and makes it hard to evaporate
Original water evaporates faster
A difference doesn't exist.
Water evaporates faster than salt water and sugar water.
The water in the salt water evaporates, leaving a dry residue of salt crystals.
If the water was pure and had no salt already mixed in it then the same 20 grams of salt would be left, as salt doesn't evaporates on the temperature at which water does evaporates.
the water evaporates and then it leaves the salt behind
Salt remain as a residue.
Water evaporates faster than salt water and sugar water.
Yes, it does. When the water evaporates, it can not take the salt with it, so if you left a glass of salt water out, when it is evaporated the salt will be on the glass.
The water in the salt water evaporates, leaving a dry residue of salt crystals.
This is salt water.
If the water was pure and had no salt already mixed in it then the same 20 grams of salt would be left, as salt doesn't evaporates on the temperature at which water does evaporates.
The warmer water is, the more quickly it evaporates.
After water evaporation solid salt remain as a residue.
Salt. You get salt flats.
Pure water is evaporated faster.
You boil the salt water so the water evaporates, leaving salt.
the water evaporates and then it leaves the salt behind
an example is that when sea water evaporates,it becomes salt.
