The fluid on your skin ( try it with rubbing alcohol ) is taking heat from your body and evaporating because it's getting warmer. Your skin feels cold because heat is being transfered out of your arm.

Why is evaporating from water from your skin a cooling process?
Evaporation is an endothermic process, absorb energy.
How do you find out the effect of evaporation on skin?
Evaporation causes cooling . The skin cools when evaporation takes place.
What is process cooling?
evaporation Cooling is a decrease of the temperature of a system or material.
Why is evaporation of water from your skin a cooling process?
In order for sweat or water to evaporate from your skin it requires heat; therefore, when it evaporates it takes some of your body heat with it.
How evaporation exhibit the cooling effect?
Evaporation needs heat energy. During the process of evaporation heat is absorbed by the other body thereby cooling it
Cooling effect of alcohol on the skin is the result of?
it is the simple principle of evaporation. The same effect can be acheived with any liquid that can evaporate at or around body temperature. Alcohol has a low evaporation point, when you apply it to your skin it draws heat energy from your skin and evaporates off, this process has a cooling effect because it is drawing heat energy from your body.
The transformation of a liquid to a gas that serves as a cooling process is?
Evaporation
Evaporation is a cooling process because?
heat is radiated away
Is alcohol evaporation endothermic or exothermic?
Always endothermic. Liquids absorb heat from the surroundings through evaporation, and keeps continuing this to regain lost energy. This produces a cooling effect in the surroundings.
How sweating works?
Sweating is a process designed to help cool your body if you get too hot. What happens is that the sweat pores in the skin exude sweat which then evaporates. The process of evaporation causes cooling.
Is heat energy being added or removed during the process of evaporation?
In condensation heat is removed In evaporation heat is added
Is condensation a cooling or warming process?
Condensation is the opposite of vaporization. When you sweat you are cooling your body off; therefore condensation is a warming process. Or Evaporation A+
