Alcohol evaporates faster than water or sweat and causes a cooling sensation on the skin as it evaporates. Any liquids do this but since alcohol evaporates faster it's more noticeable.
Or if you want a better answer
Evaporation requires energy to change from liquid to a gas, and that energy comes from whatever the liquid is on, ie; your skin in this case. The energy gets transfered from your skin, in the form of lost heat energy, to the evaporating liquid, resulting in a drop of temperature. Refrigerators use this principle to cool the inside. The faster the evaporation rate, the larger the drop in temperature. Hope this helps.
The answer is option B.
The skin is a physical
barrier, and as it, it plays an important role in order to prevent the
entrance of microbia to the body. For this reason, there is a very
little percentage of microorganisms that achieve to enter in our body, generally by food, mosquito bites, or injections.
