Which of the following statement is FALSE?
At pseudo-steady state diffusion, the level of liquid or the diameter of napthalene ball changes fast
None of the above
At pseudo-steady state diffusion, the level of liquid or the diameter of napthalene ball changes slowly
At steady state diffusion, the level of liquid or the diameter of napthalene ball does NOT change
A.At pseudo-steady state diffusion, the level of liquid or the diameter of napthalene ball changes fast
B.None of the above
C.At pseudo-steady state diffusion, the level of liquid or the diameter of napthalene ball changes slowly
D.At steady state diffusion, the level of liquid or the diameter of napthalene ball does NOT change
Explanation / Answer
option A is false.
option c is true.
In diffusion of spherical naphthalene ball, the pressure exerted by the naphthalene vapour change with respect to time but that change is too slow that we can model our system with the help of steady state and this process is also known as pseudo-steady state diffusion.
Same as in the case of diffusion of the liquid from the tube in the air.
