For example, if an open test tube with some water in the bottom is placed in a room in which the air is relatively dry, water vapor will diffuse out through the column of air in the test tube.
This thesis is developed on an existing problem for the control of distill column in the process of rosin and turpentine production by continuous vapor distillation.
