Dew point

De dew point be de temperature de air dey hia make ebe cooled to (at constant pressure) so say e go produce a relative humidity of 100%. Dis temperature dey depend for de pressure den water content of de air. Wen de air be cooled below de dew point, ein moisture capacity be reduced den airborne water vapor go condense make e form liquid water dem know as dew. Wen dis occur thru de air ein contact plus a colder surface, dew go form for dat surface top.
