Homework Statement
Hello, I will post a picture here of a question.
It states, a column of air is trapped by 5cm of mercury as shown.
What is the pressure in cm of mercury in the gas in each case?
Homework Equations
Pressure= h*g*rho
The Attempt at a Solution
I would use that equation but usually density is given in these exams.
They state for the answer to be in cm of mercury,
So my guess is for the first one it’s 76+5cm
For the second it’s 76-5cm
And for them last one it’s 76 cm no change.
How do I figure this out?
