alocohol is easy toevaporate, however, its sturcture (helping attache itself two water molecules) allows the water there to go with it.
The alcohol on our hand absorbs it's latent heat of vaporisation from the surface of our hands and evaporates.Drawing heat and therefore, cooling our hand in the process.
Due to the latent heat of vaporisation and its rapidly because the boiling point of alcohol is less
Because the alcohol on your hands absorbs it latent heat of vapo.
Alcohol has tendency to evaporate fastly so when it evaporate it takes away the heat present in the hand along with it . So it causes cooling
