Why does evaporation make you feel cooler?

When a Liquid evaporates it takes the heat of the surroundings to reach its Vapourisation State ... Thus making you fell cooler

Yes they do cool as they evaporate.\n\nWhen you heat up a liquid, it evaporates and turns into a gas. But it takes energy to pull a molecule out of the liquid and turn it into a gas, since the liquid molecules stick together and it’s kind of hard to pull them apart. That leaves a little less energy for keeping all the molecules jiggling around. In other words, they actually do cool down a little bit just as they evaporate. So, left to itself, the liquid would cool down as it evaporates.\n\nYes, liquids cool as they evaporate. In order to evaporate liquids draw heat from the environment around. The liquid that is left behind as some of it evaporates is cooler than it was before that amount evaporated. You

Sweat is continuous, but when apply oil it stops sweat from evaporating, that's the reason you feel it..

This is called evaporative cooling.\nThe water is cooler than your skin and absorbs this excess heat until it reaches evaporation temperature. As the water evaporates it releases this heat into the air which must be cooler than your body for this process to work. This is why sweating helps cool the body. The hotter and more humid the air temperature, the slower the evaporative cooling effect takes place.

I don't really understand what your question is.  In the first place, heat always flows from a warmer object to a cooler one.  That maximizes the number of possible arrangements of energy quanta, leading to an increased entropy.

Wind chill is a theoretical value for what a person feels when wind is blowing on them at a cold temperature. It is not an actual temperature, but it is what the conditions feel like. For example, 40 degrees with no wind is tolerable with a light jacket. But, if it is 40 degrees and a 20 mph wind is blowing, it feels more like 30 degrees. \nHeat index is another theoretical value for what a person feels when it is humid or dry at a warm temperature. For example, if it is 90 degrees and is about 40% humidity, it will feel like 90 degrees. But if the humidity is 80%, it will feel like 95. It also works the other way. If the humidity is 10%, it will feel like 87 because it's so dry. When it's dry, sweat evaporates almost instantly off your skin, making you feel cooler. When it's humid, the sweat can't evaporate very easily, making it feel warmer. With wind chill, there is a layer of air insulating your skin from the cold. When wind blows, it disturbs the layer and makes you feel colder.

simple, by evaporation it increases the moisture content of air, there by reducing temperature. thats' y u can feel cool breezes near lakes and other big water bodies.

Your body absorbs the vapour like a sponge...:D

It's not a matter of cold air moving toward warm air, but a matter of the air trying to find equilibrium. Cold air is denser than warm air, and cold air sinks while warm air rises. That's why we feel wind - the colder air rushes in to fill in the less dense air and create an equilibrium.\n\nThis may not be the most meteorologically correct explanation, so any weather people are free to enhance or correct it.

Because that's the temperature we reach internally, our skin is very different it does not produce heat therefore we feel the heat and cold!

The handles are powerful insulators, so they don't conduct the heat of the pan into the handles. They release the little heat that they do conduct into the air, therefore feel cool to the touch.

It has to do with humidity.  The higher the humidity level, the more chances you have of sweating and therefore it feels like your deodorant has melted.

I go outside to get some fresh air.,.Outside air just flows better,..,makes me feel good.

What a surprising question! I've never stopped to think about it, but when I do, I guess it's because there's more insulation on the face.. the fat in the cheeks plus ofcourse, our hair in some cases, so we don't feel as cold as to get goose bumps.

I grew up in a dry climate so my body learned that sweating would result in cooling.  I am now in a humid environment and my body produces much more sweat than is useful.

Evaporation is a process whereby atoms or molecules in a liquid state (or solid state if the substance sublimes) gain sufficient energy to enter the gaseous state. \n\nThe rate of evaporation depends on a number of factors:\n1. Concentration of the substance evaporating in the air: If the air already has a high concentration of the substance evaporating, then the given substance will evaporate more slowly. \n2. Concentration of other substances in the air: If the air is already saturated with other substances, it can have a lower capacity for the substance evaporating. \n3. Concentration of other substances in the liquid: If the liquid contains other substances (such as salts), it will have a lower capacity for evaporation. This is due to Raoult's law. \n4. Temperature of the substance: If the substance is hotter, then evaporation will be faster. \n5. Flow rate of air: This is in part related to the concentration points above. If fresh air is moving over the substance all the time, then the concentration of the substance in the air is less likely to go up with time, thus encouraging faster evaporation. In addition, molecules in motion have more energy than those at rest, and so the stronger the flow of air, the greater the evaporating power of the air molecules. \n6. Inter-molecular forces: The stronger the forces keeping the molecules together in the liquid or solid state the more energy that must be input in order to evaporate them. \n\nNow one can understand why evaporation of water increases in sunshine. It is primarily because of the increased temperature and probably also due to the increased flow of air during sunshine.

Yes.\n\nThe body cools itself by evaporation of perspiration from the skin.  In dry air, perspiration evaporates rapidly causing a cooling affect but in humid air, perspiration evaporates less quickly so you don't feel as cool.  You'll feel warmer at the same temperature in a humid climate.\nhttp://en.wikipedia.org/wiki/Humidity#Effects_on_human_body\n\nIn it's simplest form, the "heat index" attempts to capture this property of perceived temperature by factoring humidity and temperature into a single value.\nhttp://en.wikipedia.org/wiki/Heat_index\n\n\nSome of the weather services such as Accuweather have devised ways of expressing the perceived temperature that include multiple factors including: "ambient temperature, wind speed, solar intensity, humidity, precipitation intentisty/type, elevation, and atmospheric pressure".  The purpose of this is to try and include all factors that might affect how we perceive temperature.\nhttp://www.accuweather.com/iwxpage/adc/help/pr_realfeel_pr.htm\nhttp://wwwa.accuweather.com/company.asp?page=about\n\nWeather.com has their "Feels Like" temperature rating which is similar.\n\n\nOf course, there are situations where it is so hot that it doesn't matter about the humidity.
