Finally, we'll be including questions on Unit III material to help prepare you for topics you may encounter in the cumulative portion of the Final Exam. So think back to what you already know to answer the following questions:

Two different fluids of different densities are placed into two different U$-$tubes $(1$ and $2).$ The left branch of each U$-$tube is sealed and a pump is used to increase the pressure in it$.$

$1$

$2$

If the pressure in the left branch is raised to the same value in both cases, how do the densities of the two fluids compare?

OP$2$P$1$

O We can't say without knowing the total volume of the fluid in each tube.

OP$2$P$1$
