Answer:
Explanation:
Using Laplace's law of surface tension:
where:
P = pressure
T = surface tension
r = radius
In the longer alveoli with radius of 0.07 mm = 
; we have:
P = 
P = 
In the smaller alveoli with radius 0.05 mm = 
; we have:
P = 
P = 
The pressure difference can now be calculate as follows:
Pressure difference = 
Pressure difference =
Explanation:
He weighed silver, dissolved it in acid, and then recovered all the original silver by reacting the solution with copper. He also showed, by using iron to recover the copper, that this displacement of one metal from its salt by using a second metal was not because of transmutation, as many had held.
