But how do you calculate the pressure of the trapped air?
Wouldn't the pressure of the trapped air + pressure of the
mercury be lesser than that of the atm pressure?
Do you get the pressure of the trapped air from the first
diagram?
Like: 101000/0.42 to find pressure per metre?
And then use the answer for the next diagram?
But then again..the pressure of the air pocket in the second
diagram should be lesser because the same number of air molecules
occupy a larger space..
