Question

In the previous question I asked, I recieved an answer which told me that air needs very very high pressure and very low temperature.

A simple situation:
When we cook, and open the lid of the container, we see water droplets. But in this case, air has a high pressure but not a cold temperature. So, how does it condense?

Solution

Well, boiling water from a pot produce vapour at about 100°C, about since it depends from the pressure and the distance (temperature drop) above the water surface.
This vapour will make contact with the lid of the pot, the lid will be at a temperature well bellow the 100°C, because its upper surface is in contact with the surrounding air (let's say 30°C) but hotter than that, since heat is transferred from the pot to the lid through metal heat conduction and from the vapours reaching the lid; we may assume that the lid will reach a temperature of let's say 60°C.
Now, as vapours (100% humidity, 100°C) contact the lid at 60°C (dew temperature less than vapour temperature), will condense in drops.
