yes it is
the water is changing to a gas
see there is three most important things
Solid, Liquid, Gas
and youre changing liquid to a gas/vapour
Boiling point is a physical characteristic because the matter changes state not composition. It is not a chemical change because nothing happens to the electrons in the outer shells of any of the atoms involved. Alcohol absorbs energy with he result that it changes phase, and such a change is by definition a physical change and not a chemical change.
Yes, because igniting something will be changing the chemical composition of the particle.
Is a physical change as the alcohol is changing states
Physical change
Physical; from liquid to gas, but it's still alcohol.
It is a chemical change.
Evaporation is a physical process.

Evaporation of alcohol is a physical change.
Evaporation is a physical change- it is still alcohol. The change can be undone by colling the air and condensing the ethyl alcohol vapor back to liquid alcohol.

Dissolution is a physical change because the molecule remain unchanged.

No, it's physical.
