mean free path, average distance an object will move between collisions. The actual distance a particle, such as a molecule in a gas, will move before a collision, called free path, cannot generally be given because its calculation would require knowledge of the path of every particle in the region. In physics, mean free path is the average distance over which a moving particle travels before substantially changing its direction or energy, typically as a result of one or more successive collisions with other particles.And now for the solution you’ve been waiting for. A collection of relevant questions and answers that you may require on occasion.

What do you mean by mean free path Class 11?
The mean free path is the average distance traveled by a moving particle (such as an atom, a molecule, a photon) between successive impacts (collisions), which modify its direction or energy or other particle properties. -
Mean free path refers to the…
Mean free path refers to the average distance that a moving particle travels between successive collisions or impacts. Furthermore, the successive collisions result in modification of the moving particle’s energy or direction or any other particle properties. -

In the kinetic theory of gases, the mean free path of a particle, such as a molecule, is the average distance the particle travels between collisions with other moving particles.

Mean Free Path, Molecular Collisions – HyperPhysics Concepts
- Summary: Mean Free Path, Molecular Collisions The mean free path or average distance between collisions for a gas molecule may be estimated from kinetic theory. Serway’s approach is a good visualization – if the molecules have diameter d, then the effective cross-section for collision can be modeled by using a circle of diameter 2d to represent a molecule’s effective collision area while treating the “target” molecules as point masses. In time t, the circle would…

3.1.3: Mean Free Path – Chemistry LibreTexts
- Summary: 3.1.3: Mean Free Path Last updated Save as PDF Page ID1408 The mean free path is the average distance traveled by a moving molecule between collisions. Introduction Imagine gas leaking out of a pipe. It would take a while for the gas to diffuse and spread into the environment. This is because gas molecules collide with each other, causing them to change in speed and direction. Therefore, they can never move in a straight path without…

Concept of mean free path – Byju's
- Summary: Mean Free Path and Derivation of Mean Free Path – BYJU’S In a gaseous system, the molecules never move in a straight path without interruptions. This is because they collide with each other and change speed and direction. Between every two collisions, a molecule travels a path length. The mean free path is the average of all path lengths between collisions. In…

- Summary: Mean Free Path – an overviewInteraction of radiation with matterSyed Naeem Ahmed, in Physics and Engineering of Radiation Detection (Second Edition), 20152.1.C Mean free pathAs particles pass through a material, they undergo collisions that may change their direction of motion. The average distance between these collisions is therefore a measure of the probability of a particular interaction. This distance, generally known as the mean free path, is inversely proportional to the cross section and the density of the material,…

Still, when gas leaks from a cylinder in a kitchen, it takes some time to diffuse the molecules from one corner of the kitchen to the other corner of the room. Similarly, it takes smoke clouds to hold together for a few hours. It ensues…
