What is Pascal's Law? When gasses aren't constrained they tend to expand or contract, which depends on the pressure. You can squeeze air into tighter spaces by pressing the molecules together. In a contained incompressible fluid, any external pressure applied at one point will raise pressure equally at every point. An object placed in water is buoyed up with a force equal to the weight of the fluid the object displaces.

In a contained incompressible fluid, any external pressure applied at one point will raise pressure equally at every point.

Explanation: This law was put forward by Blaise Pascal, a French mathematician in 1648. Pascal's Law states that in a contained incompressible fluid, any external pressure applied at one point will raise pressure equally at every point. Pascal's law has been used in fluid mechanics for different applications these includes:

- the hydraulic jack used in automobile listings,

- most automobile braking systems,

-water towers, and dams.
