Also, the attempt to use science to give "phase angle" or "tan delta" would apply to the spring and dashpot model, but cannot be used for the viscoelastic model of a rubber where the viscosity is due to the need to do work to move neighboring elements held attracted by Van der Waal's forces and elasticity is the entropy effect of stretched chains returning to a random configuration.
With nonpolar atoms or molecules, weak attractions called van der Waal's forces lead to the capillary action, Broughton says.
