Does air flow create cooling?

Yes, as long as the air has a place to flow to. If you use evaporative (swamp) cooling you are creating a positive pressure inside a building, if that pressure has an outlet like windows slightly cracked, the cooler air moves farea of entry, to the area of exit.


Why does light change direction?

A useful analogy in explaining the refraction of light would be to imagine a marching band as they march from pavement (a fast medium) into mud (a slower medium) The marchers on the side that runs into the mud first will slow down first. This causes the whole band to pivot slightly toward the normal (make a smaller angle from the normal). I borrowed this from Wikipedia. This is how I think of it but I couldn't think of how to say this as well as the above statement.


What really happens to sonny in the tracey fragments?

Sonny dies. He wanders off into the swamp and drowns supposedly. Tracy didn't notice because she was too busy daydreaming of her rocker "imaginary" boyfriend. http://www.deltafilms.net/Reviews/20080426-TraceyFragments.html ^source (all the way at the bottom of the article)


What is the working principle of air conditioning?

Air conditioning is refrigeration: the removal of heat from the air. Almost all forms use evaporation, the process by which a liquid turns to a gas and in the process absorbs heat energy.Two of the major forms of cooling are:Evaporative CoolingWater is allowed to evaporate on a surface, absorbing heat. This is used in "swamp coolers" and in commercial "chillers" that work with mechanical refrigeration.Mechanical RefrigerationA liquid refrigerant (generically called freon) is circulated through a chamber where it is allowed to expand. This expansion causes liquid to evaporate into gas as the molecules absorb heat. The gas is then mechanically compressed to a liquid again, where it loses its heat outside the system. (Household refrigerators transfer this heat through coils to the kitchen air, while window and central air conditioners release their heat outdoors.)---Thermoelectric CoolingSmall portable coolers can also use electrically-driven coolers that create a heat flux to withdraw energy as electric current, albeit inefficiently.


How can you prove that particles of matter are continuously moving?

Random movement of a suspense particles in the swamp of smaller particles can be observed through motion of pollen or dust in water using Microscope. A more simple prove would be diffusion test using dye in the still water. If the molecules of the water isn't move then there can't be such thing as dissolving of dye without stirring. Trace of dye dissipation in water can show how the water molecules motion cause the dye to move with it.

Why desert cooler are not effective during rainy season?

A desert cooler, also called a swamp cooler, depends on low humidity and evaporation to cool the air. It loses efficiency when the humidity is high, such as during the rainy season. Less water will evaporate when the air is already nearly saturated with water.


Why does the desert cooler not work in the rainy season?

The desert (swamp) cooler depends upon evaporation of water for cooling. During the rainy season the air is already pretty much saturated with water vapor so little water evaporates from the cooler and they become inefficient. They are most efficient when the relative humidity is below 20%.

Home windows do have to be open when you are using a swamp cooler. You do not open them all the way, they should be opened part way.

What temperature is swamp cooler air?

It is a function of the "dew point" of the air at any given moment. If relative humidity is high, the dew point will also be high and the swamp cooler air will be relatively warm. If relative humidity is low, the dew point will also be low and the swamp cooler air will be relatively cold. A swamp cooler in Phx AZ will put out air about 30 degrees less than the outside air, and works more efficiently when the humidity outside is very low.
