This depends on many factors.
Pure water evaporate faster.
dear who ever wrote this question your so stupid
Yes, there is water on Mars but it is believed to be either subsurface (i.e., no lakes, oceans, etc); or tied up as water ice at the poles. The atmospheric pressure and temperature is such that surface liquid water would not exist for very long - it would evaporate or freeze.
Depends on the rate of supply of heat and the relative humidity. It could take forever (100% relative humidity), or be almost instantaneous (pour onto a red hot plate with < 100% humidity).
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.
The Earth will be gobbled up and be destroyed, but that is long after the Earths oceans evaporate and no lifeforms can be sustained by the planet. Of course, you'll be dead by then. Long dead.
How long a red tailed catfish can stay out of the water depends on the fish in question and how moist the fish's gills are.
Same as it is now, but instead of as much land mass . More water will evaporate to space and earth will be without water . That will happen when sun will become red giant
none of it
Pretty long
In long geological time, all (or essentially all) of the Earth's free water will be evaporated. When the Earth is engulfed by the Red dwarf stage of the Sol's life cycle, the water will all evaporate. Another condition may cause the loss of the Earth's water. This is when the interior of the Earth cools sufficiently as to halt the movement in the Mantle, and this will essentially extinguish of the Earth's magnetic Field. This will lead to the collapse of the Van Allen radiation belts, and the Solar Wind will be able to strip the Earth of atmosphere and any water vapour. These two events are a long time away. But the second of these events was probably the cause of the present condition of Mars. No water and no atmosphere (essentially).
