Rubbing alcohol evaporates so quickly on skin because your skin is pretty warm and rubbing alcohol has a higher vapor pressure (and lower boiling point) compared to water. It is known as a volatile solvent because it evaporates easily.
Chemical.
No - the alcohol in hand sanitizer is very weak - just enough to make the fluid evaporate quickly after use. The alcohol would evaporate much quicker than your body could ever absorb it into your skin.
Alcohol is volatile (can evaporate easily. When it is rubbed on our skin , it absorbs heat from our body and evaporates and we know that evaporation has a cooling effect.
NO - acetone is not good for your skin !
Rubbing alcohol can be applied directly to the skin, or it can be used to soak a pad, which is then applied to the skin. Either way, the rubbing alcohol cools the skin as it evaporates. That said, using small applications of rubbing alcohol to cool the skin will probably not be sufficient, in itself, to break a fever. Rubbing alcohol can be used as an adjunct to other fever-reducing measures, such as ibuprofen, acetaminophen, or cold bath (with the advice of a health practitioner).
no it is not rubbing acohol on your skin is a physical change because it is still rubbing acohol but it is just evaporated or it just asorbed into your skin.

You can use it if your skin is non sensitive but not a lot it may cause burning or irritation. It can be used for making pimples dry out and basically going away. But you do have to MOISTURIZE because alcohol does dry out your skin.
Use rubbing alcohol or an alcohol prep swab.
Purified Water is usually mixed in with alcohol- usually ethanol or isopropanol- to disinfect. Alcohol alone is known to quickly evaporate, the water assists in the skin/item absorbing the mixture to clean/become anti bacterial.
