Pascal’s principle, also called Pascal’s law, in fluid (gas or liquid) mechanics, statement that, in a fluid at rest in a closed container, a pressure change in one part is transmitted without loss to every portion of the fluid and to the walls of the container. The principle was first enunciated by the French scientist Blaise Pascal.
The pressure exerted on a smaller piston is greater than on the larger piston.
The pressure exerted on a larger piston is greater than on the smaller piston.
The pressure exerted on a small piston is equal to that on the larger piston.

If the second area is greater than the first area, then the second force exerted on the system should be greater than the first force.
Pascal principle states that the pressure exerted to a confined fluid is not transmitted uniformly in all direction.
Pressure exerted on the system is directly proportional to the volume.
