If the pressure on the top of a container of fluid is increased by 10 Pa, what will happen to the
pressure at the bottom of the container?
The pressure at the bottom of the container does not change because the pressure
only increased in one area and that does not affect the rest of the fluid.
The pressure at the bottom of the container increases, but by more than 10 Pa,
because the pressure increase is magnified by the height of the container.
The pressure at the bottom of the container increases, but by less than 10 Pa because
the pressure increase is reduced by the height of the container.
The pressure at the bottom of the container increases by 10 Pa because fluid pressure
is transmitted equally to all points in the fluid.

The correct answer is "The pressure at the bottom of the container increases by 10 Pa because fluid pressure is transmitted equally to all points in the fluid." This is in accordance with Pascal's principle (or Pascal's law) in fluid mechanics, which states that a change in the pressure exerted anywhere in a confined incompressible fluid is transmitted undiminished throughout the fluid such that every part of the fluid experiences the same increase (or decrease) in pressure. Therefore, if the pressure on the top of a container of fluid is increased by 10 Pa, the pressure at the bottom of the container must also increase by 10 Pa. This principle is applied independently of the shape of the container or the amount of fluid present, as long as the fluid is incompressible and the increased pressure is transmitted through a fluid at rest. To recap: Increasing the top pressure by 10 Pa will result in a uniform pressure increase of 10 Pa at the bottom of the container.
