"To the point of superconducting" makes little sense in this context. What, specifically, is superconducting? the little wire traces between the transistors?
If you made a computer "really really cold", you can overclock it / run it at above nominal speeds. This is really the only reason to "supercool" a computer.
you would need water
When unsaturated vapour is cooled down under freezing point
It loses moisture if cooled below its dew point. It becomes more dense, and that causes it to move toward areas where the air is less dense.
The temperature to which air must be cooled to reach saturation is called the dew point.
clouds form when the air is cooled to its dew point
true
Boiling point
dew point
Clouds. If that were to happen at or near ground level, you'd have fog.
Moist air is cooled below its condensation point.
