it has reached a vonchardis front
dew point
It cools.
As snow falls it will evaporate if the surrounding air is drier, and the energy required to turn water or ice into a gas is taken from that air and the air cools. Eventually it cools to saturation, where the temperature and dew point are equal or very nearly so. This temperature - where the dew point and temperature "meet" if you increase the relative humidity to saturation - is the wet bulb temperature.
Yes. As the molecules become closer, the collisions increase, increasing temperature.
It may be the coldest temperature that some locations have reached, but it's not even close to the coldest air temperature reached or certainly that which has been achieved with technology.

i think dew point.
It cools.
When a paracel of air is cooled to the temperature at which it is saturated, it has reached its dew point.

Air cooler which cools your limited area, or decreases your room temperature.

Heats with compression, cools with expansion.
