Question

how to dry up a wet dress by the process of conduction

Answer 1

In a hot air dryer, a flow of air is first heated by a heat source such as an electric heater.  As we learned earlier, increasing the temperature of the air lowers its relative humidity which accelerates the evaporation of water.  The heated, dry air flows over and around the part being dried.  Once the hot air encounters the wet part and water starts evaporating from its surface, evaporative cooling lowers the temperature of the remaining water.  The cooled water needs to acquire heat to maintain temperature balance.
