A negative pressure of 25.0 atm can sometimes be achieved
Chapter 11, Problem 80(choose chapter or problem)
A negative pressure of \(25.0 atm\) can sometimes be achieved with the device in Figure \(11.44\) before the water separates.
(a) To what height could such a negative gauge pressure raise water?
(b) How much would a steel wire of the same diameter and length as this capillary stretch if suspended from above?
Figure \(11.44\) (a) When the piston is raised, it stretches the liquid slightly, putting it under tension and creating a negative absolute pressure \(P=-F / A\)(b) The liquid eventually separates, giving an experimental limit to negative pressure in this liquid.

ANSWER:
Solution 80PE
Step 1 of 4
In the given problem, we need to calculate the height to which the water can raise due to a negative pressure of before water separates in the given device. Also, we need to calculate the how much a steel wire of same diameter and length as the capillary stretch
when suspended from above.
