5. 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. 6. Three blocks, labeled A, B, and C, are floating in water as shown in the drawing. Blocks A and B have the same mass and volume. Block C has the same volume but is submerged to a greater depth than the other two blocks. Which one of the following statements concerning this situation is false? B (a) The density of block A is less than that of block C. (b) The buoyant force acting on block A is equal to that acting on block B (c) The buoyant force acting on block C is greater than that acting on block B. (d) The volume of water displaced by block A is greater than that displaced by block B. (e) None of the above. 7. Heat is added to a substance, but its temperature does not rise. Which one of the following statements provides the best explanation for this observation? (a) The substance must be a gas. (b) The substance undergoes a change of phase. (c) The substance must be a non-perfect solid. (d) The substance must be cooler than its environment. 5. Which one of the following statements concerning a completely enclosed fluid is true?
