According to Pascal's principle, the pressure in a fluid is always?

Step 1: Analyze the question The question asks what Pascal's principle says about pressure in a fluid.

Step 2: The concept Pascal's principle states that pressure applied to an enclosed fluid is transmitted equally and undiminished to every part of the fluid and to the walls of the container, in all directions.

This is the principle behind hydraulic brakes, hydraulic jacks, and car lifts (common in Nigerian mechanic workshops). A small force on a small piston creates a pressure P = F/A. That same pressure acts on a larger piston, giving a larger force.

Step 3: Evaluate each option

• A. Dependent on density of the fluid. This is true for pressure due to a fluid column (P = ρgh), but it is not Pascal's principle.
• B. Distributed partially in all directions. Wrong. The pressure is transmitted fully, not partially.
• C. Transmitted equally in all directions. Correct. This is the direct statement of Pascal's principle.
• D. Increasing with height. Wrong. Pressure in a fluid increases with depth, not height, and this is a separate idea (P = ρgh).

Step 4: Answer

Tip: Link Pascal with "Pressure passes on equally." For Pascal, think "transmitted equally." For P = ρgh, think "depth and density."
