Scientific definitions for Pascal's law

Pascal's law
[ pă-skălz, pä-skälz ]

The principle that external static pressure exerted on a fluid is distributed evenly throughout the fluid. Differences in static pressure within a fluid thus arise only from sources within the fluid (such as the fluid's own weight, as in the case of atmospheric pressure).
