Basically title, you always hear “windchill only affects humans” but we use fans to cool things all the time?
In: Physics
Fans/wind will cool things that are hotter than their environment, but not things the same temperature as the environment
Imagine you have a bowl of hot soup, if you stir it, it can help it cool by exposing more or the hot soup to the cooler air around it, so it’ll cool faster. The soup at the center of the bowl will stay hot for a while without stirring because it’s surrounded by more hot soup rather than cool air
Now take a bowl of room temperature water, does stirring cook it down? No, because it’s all the same temperature as the environment anyways
So wind/fans are like stirring, and humans are like hot soup, wind chill is like stirring your hot soup to make it cool faster
