Describe how your bodies use evaporation to cool themselves?
your sweat evaporates, your body heat flies away with it...
Why does evaporation cool you down?
Heat must be added to a liquid in order for it to evaporate into gas. The heat energy used to do this moves into the liquid, and in the case of your body the sweat. When the sweat evaporates it takes away the heat energy used by it to evaporate, thus removing this heat energy from the skin, causing a cooling effect.
How does the skin dissipate excess body heat?
Dissipatation of excess body heat results from capillaries being expaned in order to get more blood closer to the skin's surface. The body also makes sweat, which cools the body when it evaporates.
How can evaporation be used to keep things cool?
The water (or the thing that's getting evaporated) takes away the heat with it when it evaporates
How does prespiring make you feel cooler?
When the water in the sweat evaporates it takes some of your body heat with it, cooling you down.
Why even when is a hot day the temperature of our body would not rise?
Our bodies stay at a constant temperature on a hot day because excess heat is carried from our bodies through sweat. As sweat evaporates, it carries away the heat.
How is your body cold when you perspire?
When you perspire, liquid (perspiration or sweat) is secreted from your skin. When it evaporates into the air it carries small amounts of body heat with it making the body feel cooler.

What gland is part of the bodes cooling system?
Sweat glands. Sweat is secreted through the skin, and the liquid water absorbs heat and evaporates, and carries the heat away from the skin. To restore your body, you must drink enough water as you have perspired away, along with salt and other electrolytes that were carried out to the skin, and which dry on the skin. This is why your sweat tastes salty, and why you itch when the sweat evaporates and leaves the salt on your skin.
How does sweat glands lower body temperature?
Sweat glands secrete water onto the surface of the skin. When this water evaporates it carries with it body heat, thus cooling the body and lowering temperature.
How does the skin regulate body temperatures?
Sweat glands in the skin produce perspiration (mostly water), which evaporates and carries heat away from the body - see "latent heat of evaporation".
Is heat taken away or added in evaporation?
Taken away. As a liquid evaporates, it loses heat to the atmosphere.
Why does alcohol creates a cooling sensation?
Alcohol evaporates quickly on the skin, drawing heat away from the body and creating a cooling sensation. This cooling effect is similar to when sweat evaporates from the skin, resulting in a temporary feeling of freshness.
Why is your body cold when you hair is wet?
your body is cold because the air around you is colder than the water in a shower or bath unless you are taking a hot bath.---------------------AND when water evaporates it absorbs heat, taking that heat away from you.
How does perspiration help to cool your body?
Evaporation has a cooling effect... sweat is liquid which means it could evaporate... if it evaporates then it will have a cooling effect :D
Why do you feel cool when your perspiration evaporates?
Because as water evaporates, this takes energy (heat) away from the place where the water was. This energy is called the "latent heat" of evaporation. The energy (heat) is given "back" when the water vapor re-condenses. It is this energy that drives a thunderstorm.
How do water evaporate from body's of water?
The suns heat evaporates water.
