When a chemical reaches its boiling point, it expands into a gas. The ethyl alcohol (or any liquid when it is boils) stays the same, the molecules just get farther apart. So it is a physical change.

Water, for example, once boiled to produce steam and/or water vapor, then allowed to cool to any temperature below its boiling point, will revert to its most common liquid state (the same is true of the freezing point - if allowed to warm above its freezing point, it will again revert to its most common liquid state).

Is evaporating alcohol a chemical change?
No. It is a physical change as the actual compound does not change, only its state does.
Is evaporating of water in a lake a chemical or physical change?
PHYSICAL CHANGE
Is burning alcohol in oxygen a physical or chemical change?
It is a chemical change.
Is fermentation a chemical change?
Fermenting cheese will become a chemical change not a physical change.
Is ethyl alcohol in a watch glass a physical or chemical change?
Neither. It is a chemical compound, and not a change at all.
Is courseness a chemical or physical change?
Physial change
Is evaporating alcohol a chemical change?
No. It is a physical change as the actual compound does not change, only its state does.
Is alcohol evaporating a chemical change or a physical change?
Is a physical change as the alcohol is changing states
Is sweat evaporating from your forehead a chemical change?
No. It's a physical change
Is evaporating of water in a lake a chemical or physical change?
PHYSICAL CHANGE
Is water evaporating a chemical change?
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.
Is rusting metal a physial change?
No it is chemical. The metal (for example Iron, Fe) reacts with Oxgen Gas to produce Iron Oxide. You can also tell it is a chemical change because there is a colour change.
How is evaporating water a chemical change?
Evaporation is a physical process.
Is water evaporating off the counter a physical or chemical change?
Evaporation is a physical change.
Is evaporating sea water a physical chemical or nuclear change?
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 .
Is perfume evaporating chemical or physical change?
Evaporation is a physical process.
Is water evaporating into steam a chemical or physical change?
It is a physical change because the change is reversible.
