why does it sometimes show the temperature outside is 5° but Feels like 1°. Isn’t the actual temperature supposed to be what it’s feeling like? What’s the whole purpose of having that 5° there then

If it’s windy then the it can feel colder than the actual temperature. The wind is colder than the ambient temperature

temperature measures the average kinetic energy present in the air. however, how we experience that energy can change based on other factors such as wind chill or humidity

The *real* temperature is a result of physical processes that we can measure with tools like thermometers. But there are *other* factors like humidity and wind chill that also affect how we as humans feel that temperature, and so the “real feel” temperature aims to estimate that. For instance, it might *technically* and physically be warmer than freezing outside, but due to very strong winds it might *feel* like it is much colder than freezing.

The first is important to record so that we can establish average weather and climate trends for an area over a month, a year, many years. The second is important to report so that we can dress appropriately when we go outside.

Humidity, or the amount of water in the air can affect how it feels like. Water holds more heat energy, and so has a greater impact on how much you heat up or cool down.

Wind also affects how you feel. Notice that when you cool yourself with the fan, the fan is not actually cooling the air, it feels cooler because the speed heat is transferred to air is increased. This you can imagine as newer fresh air is bombarding ar your skin as opposed to air heated by your skin sort of stagnating around you.

“Wind chill”

When the wind hits your skin, it evaporates water off it. This is endothermic because the molecules that evaporate are absorbing heat in the process. This cools you down, and is why our bodies sweat when overheated.

So the “feels like” temperature takes into account wind chill. The temperature is 5°, but because of the wind it feels the same as if it was 1° without any wind.
