it is an organic liquid

its freezing point is lower than water

its vapour pressure is 2.5 times greater than water

Alcohol is more volatile than water because its vapour pressure is $2.5$ times greater than water. A liquid vapourises when its vapour pressure becomes equal to atmospheric pressure.
