my answer -
The process is known as distillation, because adhesion is the force
between molecules of different liquids i.e mercury and water while
cohesion is the force that exists between molecules of the same liquids
i.e mercury and mercury or water and water. Diffusion is just the
movement of gaseous molecules from area of higher concentration to areas
of lower concentration through a semi-permeable membrane.
P.S
Happy to help you have an AWESOME!!!! day ^-^
