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.
Sound speeds up when it goes into water from air. Sound travels much faster in water than in air.
Yes.Additional answerThere's often some air in water, but not always. It has to dissolve to get there. It's not there automatically
As long as there is plants, we will always have air, and water just never runs out
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.
Water vapor in the air is visible in the form of mist, fog, and clouds.
Water vapor is always present in the air because water molecules are constantly evaporating from oceans, rivers, lakes, and other bodies of water, as well as from plants and soil. This constant evaporation releases water vapor into the atmosphere, where it can remain suspended as humidity in the air.
* It stays water, it leeches through the ground or evaporates always staying as water.
It gets warmer and warm air always rises.

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.
no it isn't because water is everywhere. 70% of us is water! There's about 1% of water in the air we breath and water is always in our food.
No, it is always less than one hundred percent.
