Question

Which one of the following statements concerning a completely enclosed fluid is true? (a) The pressure at all points within the fluid is independent of any pressure applied to it. (b) Any change in applied pressure produces an equal change in pressure at all points within the fluid. (c) An increase in pressure in one part of the fluid results in an equal decrease in pressure in another part. (d) The pressure in the fluid is the same at all points within the fluid.

Answer 1

Answer: (b) Any change in applied pressure produces an equal change in pressure at all points within the fluid.

Explanation: According to Pascal’s Principle, “a change in pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and to the walls of it's container.” (Openstax)
