Pascal’s law:

            Pressure, applied at any point of a liquid enclosed in a container, is transmitted without loss to all other parts of the liquid.

Experiment:

 It can be demonstrated with the help of a glass vessel having holes all over its surface.

Fill it with water. Push the piston. The water rushes out of the holes in the vessel with the same pressure. The force applied to the piston exerts pressure on the water. This pressure is transmitted equally throughout the liquid in all directions.

 In general, this law holds good for fluids both liquids as well as gases.

Applications of Pascal’s law:

 Pascal's law finds numerous applications in our daily life such as automobiles, hydraulic brake systems, hydraulic jacks, hydraulic presses, and other hydraulic machines.
