Kinetic Theory of Gases Postulates The kinetic theory of gas postulates is useful in the understanding of the macroscopic properties from the microscopic properties. Gases consist of a large number of tiny particles (atoms and molecules). These particles are extremely small compared to the distance between the particles Postulates of the kinetic theory of gases: Gases consist of tiny particles (molecules or atoms). On average, gas molecules remain far apart from each other. Therefore, the actual volume of the gas molecules is negligible as compared to the volume of the container The microscopic theory of gas behavior based on molecular motion is called the kinetic theory of gases. Its basic postulates are listed in Table 1: TABLE 9.13. 1 Postulates of the Kinetic Theory of Gases. 1 The molecules in a gas are small and very far apart However, like any other theory, there are some postulates of the kinetic theory of gases as well. Let us read in detail about these postulates of the kinetic theory of gases: During the collision process, the molecules cannot lose any kind of kinetic energy. Thus, it can be easily said that these said collisions are perfectly elastic

The kinetic theory of gases is a scientific model that explains the physical behavior of a gas as the motion of the molecular particles that compose the gas. In this model, the submicroscopic particles (atoms or molecules) that make up the gas are continually moving around in random motion, constantly colliding not only with each other but also with the sides of any container that the gas is.
. EARLY THEORIES OF GASES The kinetic theory of gases originated in the ancient idea that matter consists of tiny invisible atoms in rapid motion. In the7th century this idea was revived and used to explain, among other phenomena, the properties of gases.

Assumptions or postulates of the kinetic-molecular theory of gases are given below. These postulates are related to atoms and molecules which cannot be seen, hence it is said to provide a microscopic model of gases
Based on one of the postulates of the kinetic theory of the gases it is assumed that the volume occupied by the gaseous molecules themselves is negligibly small compared to the total volume of the gas. This postulate holds good for ideal gases and only under normal conditions of temperature and pressure for real gases Some postulates of kinetic molecular theory: Gases are composed of a large number of particles that behave like hard, spherical objects in a state of constant, random motion. These particles move in a straight line until they collide with another particle or the walls of the container. They are much smaller than the distance between particles
Assumptions of Kinetic Theory of Gases. Every gas consists of extremely small particles known as molecules. The molecules of a given gas are all identical but are different from those of another gas. The molecules of a gas are identical spherical, rigid and perfectly elastic point masses so I want to talk to you a little more about the kinetic molecular theory of gases what this basically says is that the macroscopic properties of a gas like the pressure or the volume or the temperature are just a result of the microscopic properties of the gas molecules like the position and the speeds of these molecules so V down here is speed V appears volume the idea is this gas is made of.

At high pressures, PV increases above the ideal gas value because the first postulate of the kinetic theory of gases is no longer valid. As pressure increases, the molecules are squeezed close to one another, and the volume of the molecules themselves becomes a significant fraction of the volume of the container The kinetic theory of gases is based on a basic molecule of gas. It was developed by British scientist James Clerk Maxwell and Austrian physicist Ludwig Boltzmann. The kinetic theory was established in the 19th century and developed into an important concept of modern science

Characteristics of an ideal gas:. The gases which follow fundamental postulates of the kinetic theory of gases and at all temperatures and pressures simultaneously obey both Boyle's law and Charles's law are called ideal gases.. Gases consist of particles in constant, random motion The kinetic theory of gases describes gas as a large number of submicroscopic particles such as atoms and molecules, all of which are in random and constant motion. The randomness arises from the particles collisions with each other and with the walls of the container
Alright. So we're going to talk about gases and the kinetic molecular theory. The kinetic molecular theory describes the behavior of gases in terms of motion. This theory is divided into five postulates. It's also describe how we can derive the laws to create the gas laws okay, and how they behave. Alright. So there's five postulates, lets go. The (Newtonian) kinetic energy of a particle of mass m, velocity v is given by = | | = (+ +), where v x, v y and v z are the Cartesian components of the velocity v.Here, H is short for Hamiltonian, and used henceforth as a symbol for energy because the Hamiltonian formalism plays a central role in the most general form of the equipartition theorem.
