For a monolayer of C60 molecules interacting on a plane the EOS can be written as Π + ! !! � − � = �� where A is the area occupied by molecule, and Π is the transverse surface pressure or surface energy (N/m). The 3D pressure P of a gas is analogous to the 2D tension Π or � of a liquid surface, and both can be treated within the framework of a van der Waals EOS. However, the pressure of a gas is trying to increase the volume of the gas, while the surface tension is trying to decrease the area of the liquid. Resolve this apparent paradox.
