What happens to the pressure in all parts of a confined fluid if the pressure in one part is increased? What happens to the pressure in all parts of a confined fluid if the pressure in one part is increased? The pressure everywhere increases by the same amount. The pressure everywhere decreases to conserve total pressure. The pressure everywhere increases by different amounts depending on the area of each part. The pressure in the other parts remains the same.

The pressure everywhere increases by different amounts depending on the area of each part.

Explanation:

Pascal's law (also Pascal's principle or the principle of transmission of fluid-pressure) is a principle in fluid mechanics given by Blaise Pascal that states that a pressure change at any point in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere.

When an outside pressure is applied at any point to a fluid in a container, that pressure is transmitted throughout the fluid with equal strength.
