1.	Define and explain Pascal's lawapplication of theexpansion
Answer» Pascal’s principle, also calledPascal’s law, influid (gas or liquid) mechanics, statement that, in a fluid at rest in a closed container, apressurechange in one part is transmitted without loss to every portion of the fluid and to the walls of the container. Explanation:Pressure is equal to theforcedivided by the area on which it acts. According to Pascal’s principle, in ahydraulicsystem a pressure exerted on apistonproduces an equal increase in pressure on another piston in the system. If the second piston has an area 10 times that of the first, the force on the second piston is 10 times greater, though the pressure is the same as that on the first piston. This effect is exemplified by thehydraulic press, based on Pascal’s principle, which is used in such applications as hydraulic brakes.
