This is a physical change because only the phases of the compounds change - the two compounds do no react. When evaporation occurs, the salt (NaCl) remains in its solid state while the water (H2O) becomes a gas.
Evaporation is a physical process.
Evaporation is a physical change.
It is a physical change because the change is reversible.
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.
No. It is a physical change as the actual compound does not change, only its state does.
Evaporation is a physical process.
Evaporating seawater is a physical change. Physical changes affect the form, but not the chemical makeup of a substance. The sea water is undergoing a change in states of matter, not a chemical reaction. You can undo the change by condensing the evaporated water .

Boiling and evaporation are physical changes.
Physical change- it can be undone by evaporating the water.
Water evaporating is only a physical, not a chemical change because the water can be brought back easily to its original state where as burning a match is a chemical change.
no. Those are physical changes.
