Question 2
A closed cubical chamber resting on the floor contains oil and a piston.
If you push down on the piston hard enough to increase the pressure just below the piston by an amount p, which of the following statements is correct? (There could be more than one correct choice.)
A) The pressure on the sides of the chamber will not increase.
B) The pressure at the top of the oil will increase by less than p.
C) The pressure everywhere in the oil will increase by p.
D) The increase in the force on the top of the chamber will be the same as the increase in the force on the bottom of the chamber.
E) The pressure at the bottom of the oil will increase by more than p.
