The viscosity equation further presupposes that there is only one type of gas molecules, and that the gas molecules are perfect elastic and hard core particles of spherical shape. This assumption of elastic, hard core spherical molecules, like billiard balls, implies that the collision cross section of one molecule can be estimated by σ = π ...

What Is the Kinetic Theory of Gases? The kinetic theory of gases is a theoretical model that describes the molecular composition of the gas in terms of a large number of submicroscopic particles, which include atoms and molecules.

2025年1月21日 · Kinetic theory explains macroscopic properties of gases, such as pressure, temperature, viscosity, thermal conductivity, and volume, by considering their molecular composition and motion. The theory posits that gas pressure is due to the impacts, on the walls of a container, of molecules or atoms moving at different velocities.

(a) Solids:- It is the type of matter which has got fixed shape and volume. The force of attraction between any two molecules of a solid is very large. (b) Liquids:- It is the type of matter which has got fixed volume but no fixed shape. Force of attraction between any two molecules is not that large as in case od solids.

What is Kinetic Theory of Gases? The kinetic theory of gases (KTG) tells us the method to determine the kinetic energy of a particular gas. It also helps us know the factors on which the kinetic energy of an ideal gas depends. This, in turn, will help us derive the kinetic gas equation.

In this model, the atoms and molecules are continually in random motion, constantly colliding with one another and the walls of the container within which the gas is enclosed. It is this motion that results in physical properties such as heat and pressure. In this article, let us delve deeper into the kinetic theory of gases.

2023年1月24日 · Kinetic Theory of Gases states that gaseous particles are in constant motion and undergo perfectly elastic collisions. In a collection of gas particles, the average kinetic energy is directly proportional to absolute temperature.

Kinetic theory of gases is based on the following basic assumptions. (a) A gas consists of very large number of molecules. These molecules are identical, perfectly elastic and hard spheres. They are so small that the volume of molecules is negligible as …
