Evaporating a filtrate to dryness is a physical change because it involves the phase transition of a liquid (filtrate) to a gas (water vapor) without changing the chemical composition of the substance.
Gasoline evaporating into the air

No, sweat evaporating from your forehead is a physical change, not a chemical change. The sweat is merely changing from a liquid state to a gas state without any change in its chemical composition.

Yes, it is.
Dissolve the whole salt in a warm water, then filter it out. By evaporating the filtrate, we shall get pure salt. The impurities will left on the filter paper(as these are insoluble in water).
As I have learned, it is an irreversible change, so no its not a reversible change.

No, evaporating alcohol is a physical change, not a chemical change. When alcohol evaporates, it changes from a liquid to a gas without any change in its chemical composition.

Yes, evaporation is a physical change of phase.
