dew piont temp at water vapor to condense

The dew point is not only for water, although it is the most common application. The dew point is the temperature AND pressure that a gas first begins to condense. It is when that first droplet appears. For water vapor, you will need a psychrometric chart. Certain parameters must be set such as wet bulb and dry bulb temp. Relative and absolute humidity will play a role as well.

If you need to calculate the dew point, you need a pyschometric chart and at least 2 of the following, dry bulb temperature, wet bulb temperature and/or relative humidity.

Dewpoint is the temperature at which water vapor begins to condense out of the air. As such, it's also a measure of relative humidity.

dew point is the highest temperature that gases will become a liquid.
