A bit of oil on the surface reduce water evaporation.
Well first of all, you cannot put water on the sun. It would evaporate before it got there. But if you somehow did without changing its temperature until you got to the sun then it would almost instantly evaporate and the molecules would in turn become ionized and become plasma.
you put the water in a pan and heat it till the water evapourates
Pure water is evaporated faster.
If you left water in an open container for several days in summer, the water would eventually evaporate and there would be less water than you put before but if you put in in winter, the water would eventually freeze.
Heating favors evaporation.
Yes. However, if you were to pour a gallon of water into a bowl on Mars, the water would boil and quickly evaporate because of the very low pressure.
When you put water near a window it will eventually after a couple of days evaporate.
to separate salt and water you can put it out side and let the water evaporate or to speed things up you can put it on the stove.
you have to evaporate the water.( if you want the water put a plastic cover over it.)
Yes, because all you need is heat to evaporate water. Put some water in a pot and turn on the stove. Don't put on the lid. the steam you see is evaporated water.
yes, it'll still evaporate the water.
Dont get me wrong, but you seem to be asking how to separate salt from water. I think if you evaporate water, the salt cannot evaporate, and it stays behind. However, if the light is really hot, it will evaporate the salt along with the water. (Example: If you put salt and water in a dish and hold it on top of a lit candle, the light is hot enough to evaporate water, but not hot enough to evaporate salt.
