    We are familiar with the ideal gas law in three dimensions:
    PV = nRT,
    where n = number of moles and R = universal gas constant = 8.3145 J/mol K

    To change this to two dimensions, we simply replace the V with an A (volume becomes area). This can then be applied to surfaces, because surfaces are two-dimensional. Pressure is still relevant - it is the surface tension. Surface tension can be derived from ...
