Air movement serves as the transportation system, or
‘transport mechanism’ in this process. As water
evaporates, humidity begins to form along the wet
surface. Without a means for transportation to remove
this vapor, this high humidity will retard the evaporation
process. It can be difficult to visualize how this high
humidity affects drying as generally, it is not visible.
Imagine instead a different change in state: Melting ice in
