Because alcohol has a much lower boiling point so more exaporates quicker and makes the remaining alochol cold as it consumes latent heat to evaporate.

Why do you feel cool on applying perfume or aftershave lotion?
evaporation takes energy. It gets this energy from the surface its evaporating from in the form of heat. The faster the evaporation, the greater the cooling effect. This is why we sweat, it evaporates to cool us down. perfume is mainly alcohol. This evaporates quickly hence the effect you have noticed.
Why is a child with a high fever given a sponge bath with water mixed with rubbing alcohol?
To help cool the child down. The evaporating alcohol would help with the cooling. To evaporate the alcohol needs some energy and it would take heat from the child's skin thus helping with the cooling. The water would remove heat from the skin by evaporation and conduction.
Does ice water or ice cubes cool lemonade faster?
If the initial temperature of the lemonade is equal for both the water and the ice then the cubes would cool lemonade faster because they have a lower initial temperature.
Does milk cool faster than water?
No, compared to milk, water evaporates much more quickly.
Why must an evaporating dish cool before measuring its mass?
Temperature only effects mass by a very little amount. A high school lab including chemical reactions and using a scale that measures to the hundredth or thousandths place won't be effected by temperature. One reason that you must wait for the dish to cool could be for safety precautions, or possibly just to prevent damage to the scale. It all depends on the situation.
Why does your hand feel cool when you put hand sanitizer on the back of it. What is happening to the alcohol in the hand sanitizer?
The alcohol is evaporating, sucking some warmth from your hand as it does, making it feel cool.

What cools faster warm or cool water?
No It's warm water the ? was what cools faster cool water is already cool so warm water will cool faster. Plus cool water gets warm Also back in the sixties a experiment was done Hot water froze faster than cold water by a minute . ( I remember this from the Weekly Reader report. lol lol ) I also believe it's meant to suggest when the water is at room temptureroom temperature.
Does salt water or fresh water cool faster?
who cares about water
Why might you feel cool on a hot day when you get out of a swimming pool?
because you feel the water evaporating on your scin and that cools it
Why does blowing on soup make it cool off faster?
The steam you see coming off a hot bowl of soup are the hotter, faster moving particles evaporating into the air, leaving slower-moving, cool particles behind. But these evaporated particles form a little cloud of vapor above the soup, which prevents the other hot particles from evaporating. When you blow on your soup, you blow away the vapor. This allows more of the faster moving particles to evaporate.
Does water cool down faster in smaller containers?
yes, if there is less water there is less to cool down
Does pure water cool fast?
That depends on what temperature the pure water is at. Pure water in general does cool faster, however.
Does water cool and heat faster than water?
beacause its solid
Why does warm water than freeze faster than cool water?
Mpemba effect ,water evaporates faster so it has less water so it freezes faster
