Question

A very long, closed tube is placed vertically in a
large open container of mercury. The volume of
the container is much larger than the tube. All of
the air is then sucked out of the tube such that the
inside of the tube is a complete vacuum. Which
statement best describes that height to which the
mercury rises in the tube?

A) The mercury will rise to the top of the
tube regardless of the tube’s length or width.

B) The mercury will reach a certain height
that is independent of the width of the tube

C) The height to which the mercury rises
depends on the width of the tube

Explanation / Answer

so it's based on P1V1/n1=P2V2/n2 (r and t are constant) so it's a change in volume. C) The height to which the mercury rises depends on the width of the tube Because otherwise if we had a giant tube with the mercury right on the bottom, it would reach as high as a really really narrow tube where mercury was almost full to begin with.
