why does air cool down the more faster it is moving LYA?

If you are talking that it feels cooler to you, it is because it evaporates moisture that is on your skin and that makes it feel cooler. Even if you are not sweating to where you can see the moisture, it is there.

The hotter air is, the faster the molecules are air move around, bashing into things.  That mass of moving molecules is what keeps a balloon inflated-its literally uncountable trillions of tiny molecules acting like tennis balls banging around.  Increase the heat, and those molecules go faster, and hit the surfaces harder. They also spread out more, which is why hor air is lighter than cold air...less density of molecules. You put a fire in a bottle, and the air molecules move faster, and get more dispersed.  It fills the balloon, because of this expansion of the air.  As it cools down, the molecules collapse in closer together and move more slowly, and thus the balloon collapses.

the air at the path of the rotating blade of the fan is forced to flow. pressure is directly proportional to the speed of the fan blade

Newton's law of cooling deviates when there is a large temperature difference between the body and the surrounding (about 30 + degrees) .

The higher you go the thinner the air, if there is less air then there is less mass to hold the heat from the sun.

The rate of cooling is directly proportional to the difference in temperature of the system with the surroundings.\nThis is why a cup of tea cools from about 70deg to 60 deg in much shorter time than it takes to cool from 40deg to 30 deg if the room temperature is constant in both cases,say 25deg.\nThis is a common life experience.

actually the hot air because of its lighter weight than cold air tends to go up and so cold air because of its more weight than hot air tends to come down and replace the hot air.

The simplest answer I can give you is that the air doesn't absorb much heat from the sun (sunlight passes through it), while the ground does (the exception is ozone, which does absorb more radiation, and thus higher up in the atmosphere, there is actually a warm layer).  So the ground is actually what is doing the heating, and the higher you go in the atmosphere, the further you are from the ground, the cooler the temperatures.\nOf course mountains are ground... but air at the same height mixes about quite a lot, so while air near a mountain might be a bit warmer... the air in other places at the same height is well above the ground, so it's cooler overall.\n\nIn addition, air cools as rises, a second reason why its cooler higher up in the troposphere.\n\n\nSpace is really really really cold!  It's for the same reason.  The light from the sun itself isn't hot... it's when its absorbed by something, which heats it up.\n\nHope this makes sense, let me know if there is anymore I can help with here,\nGod bless,\nShane

That is adiabatic cooling (by expansion). When air is forced to expand (like when it rises) it will become cooler.\n\nWhen air is forcefully compressed, that is adiabatic heating.\n\nThe answer is ADIABATIC TEMPERATURE CHANGES

Fan increase the speed of air, Air will do the rest.  Excess Temperature will desipate into air. Air will carry more heat In less time.

I agree with rocketman.  However if what you are talking about is when exhaling slowly your mouth is wide open (like when you warm your hands) vs blowing fast when you purse your lips (like blowing on your soup to cool it) then it is due to the expansion of the air, after it is adiabatically compressed by passing thru your puckered lips, which causes it to cool down.

The ice water will cool quicker.  The reason being, that the water will cover the entire surface area that you are trying to cool.  \n\nThat being said, it also won't last as long because it also has more surface area for the cooling to escape.

the science between the movement of a rocket ship is governed in the third law (i think). The law of action and reaction.\nactually the air acts as a friction. but in space the rocket will fly faster because space is frictionless, due to no air.\nthe flame coming out from its butt's side is opposite to where the rocket is moving.\nthe flame is going < < < = = = \nwhile the movement of the rocket is = = = > > >\nLaw of action and reaction.

Because the air spreads out, and as it spreads out it retains less heat.\n\nAnd while cold air does sink and hot air rises, as cold air does get lower in altitude it warms up, and hot air cools as it rises. \n\nI live in the foothills west of Denver so I see the rising/falling air thing firsthand. In the winter we get this air that 50 miles to the west was part of a blizzard. As it descends the mountains, it dries out and heats up sometimes bringing temperatures in the middle of the winter into the 60's or 70's.

It depends on the temperature of the water and the air but if they are the same, then the ice in the water will melt faster because water is a better conductor for heat.

You have it backward.  The temperature is dependent on some function of time not the other way around.

The most plausible answer is 3.\n\n- As air expands, it does cool.\n- Cooler air is able to hold less water, so is saturated far quicker.\n- When air is saturated, water droplets will condense out of the air on many available surfaces, including on lenses.
