I cant figure this out and can use a little help!?

Question

the air contains a certain amount of water vapor. The air then begins to cool, eventually the air reaches the dew point. What is the dew point and what would form at this point?

Answer 1

The dew point is the temperature at which the relative humidity reaches 100 per cent -- the air has all the moisture it can hold, and no more can be held.  The dew point depends on the partial pressure of the water vapor in the air, and can be measured with a wet-bulb thermometer.

Answer 2

warmer air (gas) can hold more moisture (way to remember this is that at boiling temperature steam holds a huge amount of water). Colder air cannot hold as much moisture, so if you cool humid warm air far enough, it will come to the point where the air is saturated (is holding maximum amount of water possible for that temperature and humidity level); any cooler and water starts to condense and produce dew or rain.

Answer 3

I seem to remember that it is the temperature where the air cannot contain the water as a vapor, so some condenses out as a cloud or fog.  Forms around dust particles as nuclei.

Answer 4

When the air is cooled, the water vapor condenses into water. The temperature that this happens at is called the dew point.
