What does pascal's law apply to?

Pascal's principle. Pascal's principle (also known as Pascal's law) states that a change in pressure applied to a closed liquid is transferred without diminishing to all parts of the liquid and the walls of the container.
How is pascal's law used?
Hydraulic brakes work according to the Pascal principle. The operator applies a force of 100 N. This force is increased with a simple lever and again with the hydraulic system. Each of the identical receiver cylinders is given the same pressure and therefore produces the same output force F2.

What is the significance of pascal's law?
Pascal's law or principle, the foundation of fluid mechanics, was discovered more than 350 years ago by French mathematician Blaise Pascal. This means that the pressure change that occurs at any point in a closed liquid is transmitted evenly in all directions. When you apply pressure to a trapped fluid, it is evenly distributed instead of decreasing.
