Adding a solute, like salt, to a solvent, like water, changes a few physical properties, some of which have to do with evaporation. Adding a solute reduces vapor pressure, preventing some water molecules from escaping from a liquid to a gas. Adding a solute also increases boiling point. So salt water would evaporate more slowly than pure water.
There are a couple of factors here that make it impossible to predict. In the dark, the plain water should evaporate more readily ("faster", all other conditions being equal). However, out in the sun, the food coloring may cause the water to absorb more energy from the sun's light, and therefore get hotter, which could easily negate the (probably small) colligative effects.
Yes it does.
Yes it does.
yes
heat it to a higher temp
Plain water evaporate faster.
yes!
The difference is not significant.
yes
Probably slower, since it has less concentration of water.
salt soaks into the water and makes the water hard to evaporate because its too thick. Ms.Melissa is my friend at Charles Ellis
Water evaporate faster in countries with a warm climate.
Salt water will evaporate faster.
No, water with syrup evaporate faster.
Baking soda is a solid, therefore it will not evaporate even when mixed with water. The water will evaporate and leave the baking soda behind.
Yes, because when salt is put into water, they can also act like magnets. Attaching to opposite particles. The salt molecules also push down the water molecules so the water molecules have to get enough power to evaporate. Which makes plain water evaporate faster.
Soda doesn't evaporate faster then plain water becasue the molecules in soda are colsely packed together which makes it harder to evaporate. The molecules in plain water evaporate quicker because they are less packed together and don't attract as the molecules in soda do.
