Chapter 14.4, Problem 44LC

Interpretation Introduction

Interpretation: To explain the distinguishes between diffusion and effusion

Concept Introduction: A huge number of microscopic level particles, including atoms and molecules, are used in the kinetic theory of gases, a conceptual model, to characterize the molecular makeup of the gas.

Answer to Problem 44LC

The capacity of gas to pass through a small aperture is known as effusion. The capacity of gases to mingle with one another, typically without the presence of a barrier, is known as diffusion. Effusion happens when the hole's size and aperture would be less than the molecules' mean free path.

Explanation of Solution

The difference between diffusion and effusion can be shown as:

Diffusion	Effusion
It can be found in all states of matter	It can be found only gas particle
Molecule shows collision	No collision between this particle
It will be slower than effusion	It will be faster than diffusion.

Diffusion and effusion have certain commonalities in addition to their differences, both processes use a concentration gradient. Diffusion but also effusion of molecules is both a continuous and random process. And neither of them needs the energy to transport molecules.
