According to Pascal's principle, how does pressure from a hand squeezing a ketchup bottle move throughout the ketchup?
Pepsi [2]

- According to Pascal’s principle, for a certain fluid in a totally enclosed system, a change in pressure at a given point in the fluid is transferred to all points in the fluid, as well as to the enclosing walls.

- This is illustrated by the fact that the pressure inside an enclosed system is the same according to the relation [ pressure = force/area ]. Therefore, the change in pressure resulting from squeezing a ketchup bottle will be transferred equally to all parts of that bottle as well as its internal content.

- That’s how hydraulic machines, such as garbage trucks and hydraulic lifts function..
