The weather instrument below is used to determine dewpoint and relative humidity.
The reason this instrument can be used to
measure atmospheric moisture is because
(1) As water evaporates and leaves the
atmosphere it adds energy to the wet bulb
thermometer
(2) Water vapor is always cooler than dry vapor
(3) As water evaporates and enters the
atmosphere it removes energy from the wet
bulb thermometer
(4) The more moisture an atmosphere has the
easier it is to evaporate

bulb temperature of a hygrometer is 19oC and
the wet bulb temperature is 12oC ?
