Answer 1

✌️✌️HEY MATE..... ☺️☺️

HERE IS YOUR ANSWER ✌️

Evaporative cooling is the conversion of liquid water into vapor using the thermal energy in the air, resulting in a lower air temperature. ... The evaporation rate depends on the temperature and humidity of the air, which is why sweat accumulates more on humid days, as it does not evaporate fast enough.

I HOPE IT IS HELPFUL.. ❤️✌️❤️
