Why do I feel cold when I get out of the pool?

Afterdrop is the phenomenon of your body temperature continue to drop even after you get out of cold water and into a warmer environment – so that you feel colder 10 or 40 minutes after you exit than you did in the water. When you swim, your body shuts down circulation to your skin, pooling warm blood in your core.

When you have been swimming and you come out of the pool you may feel cold use your understanding of endothermic processes to explain why?

Answer: The reason is that when you get out the water on your skin will start evaporating quickly, especially if there’s a bit of wind blowing on your skin. Evaporation is an endothermic process, this means that the water, turning into vapour, will take heat away from your body.

Why does one feel cold coming from a swimming pool into windy air than into still air at the same temperature?

This effect is very apparent if you have gotten out of a swimming pool on a windy and dry day. The wind evaporates moisture from the body. Since evaporation is a cooling process and absorbs latent heat away from the body, the person feels colder.

Why do you instantly feel cold after getting out of the pool on a dry windy afternoon?

“Evaporation is a cooling process,” said AccuWeather Senior Meteorologist Dave Dombek. “If you step out of the pool or a lake, you get a chill because the air is very dry, and that water almost instantly starts to evaporate off of your skin so that it cools it.”

Do exothermic reactions feel cold?

In an endothermic reaction, the system gains heat as the surroundings cool down. In an exothermic reaction, the system loses heat as the surroundings heat up. An endothermic reaction is when heat is needed by the reaction, so it draws heat from its surroundings, making them feel cold.

Why are some reactions cooled?

They absorb heat energy from their surroundings. This means that the surroundings of endothermic reactions are colder as a result of the reaction.

Why do we feel cold in water?

The reason the water feels colder than air is because water is the better conductor of the two. Because the water takes more heat from your body, and quicker, it feels colder.

Why do humans shiver?

And when you get cold, you shiver automatically. A shiver is caused by your muscles tightening and relaxing in rapid succession. This involuntary muscle movement is your body’s natural response to getting colder and trying to warm up. Responding to a cold environment, however, is only one reason why you shiver.

Why do cold packs feel cold?

As an example of an endothermic reaction, when the chemical ammonium nitrate is dissolved in water, the resulting solution is colder than either of the starting materials. This kind of endothermic process is used in instant cold packs. As a result, the water cools down.

Why does an endothermic reaction feel cold?

Endothermic reactions are the opposite of exothermic reactions. They absorb heat energy from their surroundings. This means that the surroundings of endothermic reactions are colder as a result of the reaction.
