The cause of condensation in general is due to the temperature of a surface being lower than the
dew point of the surrounding area. The dew point is the temperature at which a given volume of air
with a given water vapour content is completely saturated. Since air can hold an increased amount
of water vapour with increased temperatures. and vice- versa, lowering the temperature of air below
the dew point will cause condensation to occur. This can happen when the air comes into contact with a cooler surface (eg. the side of a cool beverage gIass), or simply through cooling of the air itself, which is how rain and snow form.
