Field Theory
No water vapor is added to or removed from a sample of air that is cooling, so the relative humidity of this sample of air will
remain the same.
be lower.
be higher.
the answer depends on the temperature.
remain the same.
be lower.
be higher.
the answer depends on the temperature.
Field Theory
Anytime a temperature difference occurs, you can expect
cold to move to where it is warmer.
energy movement from higher temperature regions
no energy movement unless it is warm enough, at least above the freezing temperature
energy movement flowing slowly from cold to warmer regions.
