Answer 1

alocohol is easy toevaporate, however, its sturcture (helping attache itself two water molecules) allows the water there to go with it.

Answer 2

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.

Answer 3

Due to the latent heat of vaporisation and its rapidly because the boiling point of alcohol is less

Answer 4

Because the alcohol on your hands absorbs it latent heat of vapo.

Answer 5

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
