Interpretation:
The effect of mass of gas particles on the rate of effusion and diffusion needs to be explained.
Concept introduction:
Gas is one of the physical
The particles of gas have high kinetic energy and exhibit different characteristics compare to liquid and solids.
Answer to Problem 9SSC
Explanation of Solution
Due to high kinetic energy, gases can diffuse and effuse. The diffusion of gases is the dispersion of particles throughout a container whereas effusion occurs through an opening. The relation of effusion and diffusion of gases can explain with the help of Graham’s law.
According to the Graham’s law of effusion/diffusion, rate of effusion/diffusionof any gas is always inversely proportional to the square root of the mass of gaseous particles. The mathematical expression for this law is:
In terms of time for gases; we can write as:
Thus,
