– If air temperature is consistent in a room, why does air from a room fan feel cool on our skin? It’s the same air with the same temp… just faster
In: Biology
We cool through evaporative cooling – water, when it goes through a phase change from liquid to gas (evaporation) requires a bit of energy to make the leap to gas form. It pulls that energy from its surroundings- which is you if anything is evaporating from your skin’s surface. Evaporation is sped up when you blow more air against the evaporating material. If there is nothing to evaporate, the is no temperature change.
