State Pascal's law.
(N/A) Pascal's law states that the pressure applied to an enclosed fluid is transmitted undiminished to every portion of the fluid and to the walls of the container.
Mathematically,if an external pressure $P_{ext}$ is applied to a confined fluid,the change in pressure $\Delta P$ at any point within the fluid is equal to the applied pressure,i.e.,$\Delta P = P_{ext}$.
