Any impurity reduce the rate of evaporation.
Adding more salt OR evaporation the water.
Evaporation is a physical change.
No, evaporation is a change from liquid to gas (water vapour).
evaporation
Evaporation changes water from a liquid to a gas by adding energy to break the bonds between water molecules. Condensation changes water from a gas to a liquid by removing energy so that the molecules come closer together and form liquid droplets.
No, evaporation causes a change in the state of matter (liquid to solid) which is a physical change
I'm 83% sure that adding water to soil is a reversible change because you can evaporate the water and muddy soil would be left in the container or petri dish. Ask a teacher if you still aren't sure.

In evaporation, the surface of the water begins to change from a liquid to a gas.
