The boiling temperature is dependent on the ambient pressure, decreasing as the pressure decreases below atmospheric andincreasing for super-atmospheric pressures. For water, this data issummarized in ...

At a higher dew point of, for example, 70 F (21 C), most people feel hot or "sticky" because the amount of water vapor in the air slows the evaporation of perspiration and keeps the body from cooling.

Supersaturated air literally contains more water vapor than is needed to cause saturation. Water vapor begins to condense onto impurities (such as dust or salt particles) in the air as the RH ...
