Explain How evaporative cooling leads to a reduction in body temperature?

Evaporative cooling in mammals is essentially done by through, using body heat to heat up the sweat (moisture to gas) and once the sweat evaporates, the heat taken away with it.

How does air movement improve comfort?
When humans perspire, the water evaporates, cooling the skin. Moving air increases the evaporative effect, making it seem cooler.
How does volume affect temperature?
Normally there is no affect. In a gas, a CHANGE of volume of a single body, will give a change in temperature. If a gas is compressed the temperature will increase. If a gas is allowed to expand, there will be a reduction in temperature. This principle is used in diesel engines, to ignite the fuel by compression and fridges, where an expansion of gas causes cooling.
Changes in temperature that result from the cooling of rising air or the warming of sinking air are?
Adiabatic
How does the body keep its temperature?
Constant body temperature is maintained by warm blooded organisms - birds, mammals. The body temperature is maintained constant irrespective of an increase or decrease in temperature of the surrounding. The constant temperature is maintained by temperature haemostasis. This is achieved by altering the metabolic rate and rate of perspiration and urination. Maintaining constant temperature is also called as homeothermy.
Why does hot water cool quicker in the first 5 minutes?
This is because of newtons law of cooling, the rate that the water cools is proportional to the difference between the temperature of the water and the temperature of the surroundings. So, as the water is hotter it cools faster, as it cools down the rate of cooling decreases.
What is better for cooling refrigerated or evaporative?
Refrigerated cooling is far better. The reason being is that if you want a 'real' cool on a hot day evaporative cannot provide this. Once the temperature rising over 30 then evaporatives performance is serverely let down. On the other hand refrigerated pro vides you with a total reduction in temperature and provides you with better comfort
A system that cools the air by spraying water into a tower is called?
Evaporative cooling
What is the difference between cooling and chilling?
Chilling is the reduction in temperature of the required solvent below than its wet bulb temperature while the rest is considered as cooling i.e. if we are only reducing the temperature of solvent to an extent such that the final temperature is above its wet bulb temperature than it will be considered as COOLING.
What do you call the process of cooling off or stabilizing body following perspiration?
The process of cooling off or stabilizing the body following perspiration is called thermoregulation. It allows the body to maintain its core internal temperature.
Panting by an overheated dog is an example of what?
Evaporative Cooling.
Why is a cooling triangle used in food technology?
Evaporative cooling triangle hat keeps your head cool.
Sweating cools the body by what?
The cooling happens due to the sweat evaporating away from the skin.
What does it mean to have evaporative cooling?
A device that uses evaporative cooling cools air through the evaporation of water. The evaporation of water enables a very quick transfer of heat, enabling many applications.
Explain how radiational cooling at night produces a radiation temperature inversion?

What cools the body by giving off sweat or perspiration?
evaporative cooling
How does evaporative cooling work?
Evaporative cooling works best in climates with low humidity. It works by passing air over streaming air by way of a powerful fan. As the water evaporates, it causes the air to cool.
How does your body maintain heat homeostasis by using perspiration?
Perspiration cools the body through evaporative cooling. As the sweat is turned to a vapor (drying from the skin) heat is absorbed from the body. http://www.answers.com/evaporative+cooling
