Which of the following statements about Pascal’s principle is true?
A. It is valid only for incompressible fluids
B. It explains why light objects float
C. It explains why the pressure is greater at the bottom of a lake than at the surface
D. It is valid only for objects that are less dense than water
E. None of the above are true
The Attempt at a Solution
The answer is suppose to be E. I thought it was A. I thought Pascal's principle was only applicable to incompressible fluids.
So if A isn't true, then is Pascal's principle true for gases? What are the limits of pascal's principle?
