SURFACE tension, σ and viscosity, η, are regarded as manifestations of van der Waals' intermolecular forces of attraction. If, therefore, rise in temperature merely separates the molecules of a liquid ...

In general, friction between two macroscale surfaces is proportional to normal force. However, the frictional characteristics of nanoscale surfaces cannot be fully described by the framework of ...
