Abstract
The laws expressing conservation of momentum and energy apply to any isolated
system, but these laws are violated for highly viscous liquids under laboratory
conditions because of the unavoidable interactions with the measuring equipment
over the long times needed to study the dynamics. Moreover, although particle
number conservation applies strictly for any liquid, the solidity of viscous liquids
implies that even this conservation law is apparently violated in coarse-grained
descriptions of density fluctuations.
