What happens to water vapor as air pressure increases?

As described by the ideal gass laws, P1 V1 = P2 V2. This means that, as the pressure increases, the voulume of the contained vapor decreases and condences.

Do you mean water cycle?\n\nWater vapor in the air is part of the water cycle. Water vapor is a gas. Water vapor is a variable gas in the atmosphere being higher in places near water sources esp. the ocean.

Water molecules in the air are continually shifting from liquid to vapor. As the Brownian motion and swirling air currents or breezes are moving them around. \n   Thus some of the water at 100 % humidity will be condensing on cooler surfaces while others are evaporating from warmer surfaces eg. your skin.\n   P.S. Your question didn't say but I hope you are standing under a umbrella or something cause at 100% humidity it's likely to be raining. \n\n  Also humidity is relative to air temperature so if the sun is shining during this sun shower, the true quantity of vapor in the air may continue to rise, while humidity actually falls.\n  Nature is truly a conundrum, and even the best super computers, and weather models fail to predict what the weather will do.\n So don't strain your brain.

It gets cooler as you go higher in the atmosphere. The water vapour in the air condenses on the dust particles forming tiny water droplets. These droplet float in the air. Such clusters of droplets is what we call clouds.

The water vapor which is released through the combustion of the gases becomes like fog and converts to water droplets when cooled in the air. This is just like the clouds

Clouds are formed essentially by water vapours.The uppermost layer of waterbodies like sea,river,ponds etc(specially sea) are in the process of evaporation always.now water vapour is a gas and due to the fa that the surface of the waterbodies and the earth is hotter,the watervapour expands its volume.As you must be knowing density of an object is its mass divided by volume.Mass being constant,if volume increases density decreases and the water-vapour getting lighter goes up.There the temperature being less ,the water vapour condenses into water-droplets and floats as clouds,

It's the change in air pressure which causes it.

As a general rule, warm air rises and cool air sinks\nit expands and becomes lighter as the molecules of air move farther apart

A liquid boils when its vapor pressure equals the pressure above the liquid.  At a given temperature, the vapor pressure of a liquid is constant.  At higher altitudes, the atmospheric pressure (the pressure above the liquid) is less than it is at lower altitudes, so water will boil at a lower temperature.

the water is relesed as vapor from the liquid when the liquid is heated. Water changes phase and becomes gas, its called evaporation.

Pressure will increase if temperature increases, assuming that the container remains at a constant volume. Because the molecules are moving faster, they collide more often with the walls of the container, so the pressure goes up.\n\nThis is demonstrated by Gay-Lussac's Law, which states that that for a fixed amount of gas (fixed number of moles) at a fixed volume, the pressure is proportional to the temperature, so:  P/T = constant.\n\nIn case you need to know this for a test, and easy mnemonic  is "Pete and Tom are Gay" (Pressure and Temperature are proportional according to Gay-Lussac).

If you consider "pressure" as the force of molecules striking the surface and the molecules are randomly moving about, then they will strike all surfaces equally.  Since gas molecules are very free in their motion, they quickly react to equilize any changes in the system.  So if temperature rises, the molecules move faster, strike the walls harder and pressure rises.

Lets look at gas in a balloon.  Lets pretend we can see the gas molecules buzzing around on a micro-scale.  At the boundary of the gas and the surface there are always some of these molecules hitting the surface.  The molecules hitting the surface, much like you pushing on a surface, creates the pressure.  So, the faster the molecules are traveling (due to a rise in temperature) the harder they will impact the surface.  Also if there are more molecules present, more will be hitting the surface and also increase the pressure.  This can be verified by analyzing the ideal gas law, PV=nRT.  Where P=Pressure, n=amount of gas molecules, and T=temperature.  We can see if we raise the n or T the pressure must rise also, assuming a constant V(volume).\n\nOn a macro-scale, such as our atmosphere, the gas has a mass just like anything else.  Although the mass is small, there are miles of gas so the total mass has a noticeable affect here at the ground.  We don't notice the pressure because we are used to it (sometimes you may notice it when your ears 'pop' driving up or down a large hill) but the atmosphere is exerting pressure on everything.

It should increase in size.\n\nThere is less water pressure exerted on the bubble when it is closer to the water surface. Therefore the internal pressure of the air bubble should increase the size of the bubble.

water vapors are always present in athmosphere. Remember that when you boil water and it reaches 100 dgs Celsius, it begins to evaporate, producing vapors. So, the opposite happens when the temperature drops down, water vapors turn liquid and, if it is cold, I mean under 0 dgs, they turn into ice and fall down on earth as snow flakes. This is called Nature's Water Circuit ;)
