Its is related to "relative humidity", which is a
measure of the amount of actual water vapor in the air compared to the
maximum amount of water vapor the air can
hold at a particular temperature. Warmer air can support more water vapor than cold air. As warm
air comes in contact
with a cold window pane, it's temperature is lowered and the water vapor
that it can no
longer hold condenses. If the temperature of the pane is below 0°C
(32°F). that water
freezes to become ice on the window pane.
