Are you aware of Pascal's principle? Take this informative " Pascal's Principle Quiz" to test your knowledge. 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. If you have a physics test then it's the perfect quiz to test your basics. Good Luck! .
