Every liquid has a boiling temperature at which it evaporates. This can change by mixing solvents (e.g. adding salt to water) or changing the pressure (e.g. pressure cooker). And yes, solids can do directly from soild form to gas, but it is called sublimation. The best example of this is dry ice's "smoke", which is frozen CO2 turning into vapor CO2.

I think it's the water only that evaporates.
If you spill milk, the water aspect of it will evaporate, leaving behind a milk stain of what was left. The same is true of oil or blood.
Pure water on the other hand should evaporate sans stain.
That's just what I think, as I didn't look it up or anything.

Not only liquids but solids also evaporate. It has to do with something called vapour pressure. Some molecules of the substance are always present in two or more phases at the surface.

Even metals evaporate.. Filament evaporation is what causes light bulbs to burn out.
You will get evaporation whenever the vapor pressure of the material exceeds the ambient air pressure. So, you have to get the temperature of the material high enough to vaporize.

All liquids evaporate, different liquids evaporate at different temperatures

all liquids evaporate what is left behind is the solids in the liquid

this is hard to explain, so look up evaporation on wikipedia
