If the temperature of a place increases suddenly, the

Solution

Relative humidity is the ratio of the partial pressure of water vapor in an air- watermixturetothesaturated vaporpressureof water at a prescribed temperature. The relative humidityofairdependsnotonlyontemperature butalsoonthepressureofthesystemofinterest. If the system at State A is isobarically heated (heatingwithnochangeinsystempressure)then the relative humidity of the system decreases because the saturated vapor pressure of water increases with increasing temperature.
