Answer:
Evaporation of sweat off the skin is what actually makes our skin feel cooler, rather than temperature.
Explanation:
If you are outside on a hot and humid day, you are sweating because you are hot, but the sweat does not evaporate very well. This makes you feel more hot and also makes you have that "sticky" feeling. hope this helps you :)
Condensation is the phase change from gas to liquid. You can see condensation in the real world if you have a very cold drink. A bottle of water filled with ice will attract water vapor from the air, and it will condensate around the bottle because the temperature is lower, which facilitates the phase change. The outside of the bottle will contain a bunch of water droplets.
Hope this helps!!
