No, it is not always pure. In nature it is considered the purest form of water, which it is. However as it falls to the ground it mixes with a large number of impurities present in the air and hence becomes impure.
That drain pipe is meant to remove condensed water from the chmber where the air is blown through the system, if there is air coming through there it just means there is no water in the line that has condensed. many units turn the drain tube upward slightly so a little water always stays in the pipe pereventing the escape of cold air. It works like a P trap on your sink.
Water has a higher density than air. Anything that is less dense will float. The tube's covering is not enough to make it sink when filled with air. That is also the reason that oil and water don't mix.
The dragon fish breaths in air from the water so keep the tank well filtered, or have air bubbles.
no
As long as there is plants, we will always have air, and water just never runs out
Yes.Additional answerThere's often some air in water, but not always. It has to dissolve to get there. It's not there automatically

Air and water droplets together create fog.
No air or any form of gas will always rise to the surface (as a bubble)
Humidity is a measure of water in the air. Humidity is always in the air dry or wet.
* It stays water, it leeches through the ground or evaporates always staying as water.
Water vapour is a constituents in air because water vapour rises in the atmosphere & is always present in the atmospere in some or the other quantity.Also 0.0001% of air consist water vapour
The water content in inspired air is variable because of the different atmospheric conditions. When it is very hot and dry there will be less water and when it is rainy and wet there will be a lot of humidity.The humidity varies because of the whether conditions. The water content is always higher in expired air because some of the moisture in the cells are evaporated out of the body.
It gets warmer and warm air always rises.
Air is more buoyant than water because air is less dense than water, and everything the thing that is less dense is always more buoyant than what is more dense than it.
