It sounds like you are presenting two possibilities: water evaporates on your skin, or water evaporates 'from the air'. The answer is both. Sweating is one of the body's cooling methods. Moisture appears on the skin out of the sweat glands, and then evaporation takes over. Evaporation is a cooling process; the sweat absorbs heat from the body, and the resulting vapor then moves to the air. The vapor is effectively transporting body heat away from the body. On a muggy day we sweat, but because the air is laden with water vapor already, it has less tendency to evaporate. It remains moisture on our skin giving rise to discomfort and, of course, not much cooling effect. It is similar when we get out of the shower or tub. You feel coolness then not only because the air around you cools down, but also because lots of moisture on your skin is evaporating into the air.
When water eaporates form the skin, it takes some of the heat from your body, cooling you down. Often if I'm too hot just putting some water on myself will greatly cool me down.
This is because the water requires heat to evapourate, and so take sit from you, then evapourates, leaving you with slightly less heat.
Since evaporation requires energy, the skin will cool down.
The intermolecular forces between water molecules are lowered and some molecules escape in the atmosphere.
Liquid water is transformed in vapors.

The surface become colder.

Sweat glands. Sweat is secreted through the skin, and the liquid water absorbs heat and evaporates, and carries the heat away from the skin. To restore your body, you must drink enough water as you have perspired away, along with salt and other electrolytes that were carried out to the skin, and which dry on the skin. This is why your sweat tastes salty, and why you itch when the sweat evaporates and leaves the salt on your skin.
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.
Most likely, the water bubbles very much and it might come out of the kettle.

Process called Convection.
When milk gets warm, some of the water evaporates. The "skin" is milk from which most of the water has evaporated.
Water is transformed in vapors; the volume of lake decrease.
The temperature remain unchanged.
Water evaporates from the skin which cools the body.
What happens to evaportaed water? How does water evaporate?
Evaporation. The ammonia evaporates faster than the water and cools the skin.
