The kinetic theory of gases is a simple classical model of the thermodynamic behavior of gases. It treats a gas as composed of numerous particles, too small to see with a microscope, which are constantly in random motion.
Kinetic theory of gases, a theory based on a simplified molecular or particle description of a gas, from which many gross properties of the gas can be derived. Such a model describes a perfect gas and its properties and is a reasonable approximation to a real gas.
State the major concepts behind the kinetic theory of gases. Relate the general properties of gases to the kinetic theory. Gases were among the first substances studied in terms of the modern scientific method, which was developed in the 1600s.
Kinetic theory explains the behaviour of gases based on the idea that the gas consists of rapidly moving atoms or molecules. This is possible as the inter-atomic forces, which are short range forces that are important for solids and liquids, can be neglected for gases.
The kinetic theory of gases explains the three macroscopic properties of a gas in terms of the microscopic nature of atoms and molecules making up the gas. Usually, the physical properties of solids and liquids can be described by their size, shape, mass, volume, etc.
The kinetic molecular theory of gases (KMT or simply kinetic theory of gases) is a theoretical model that explains the macroscopic properties of a gas using statistical mechanics. These properties include the pressure, volume, and temperature of a gas, as well at its viscosity, thermal conductivity and mass diffusivity.
Our theorem, applied to the $r$-atom molecule, says that the molecule will have, on the average, $3rkT/2$ joules of kinetic energy, of which $\tfrac{3}{2}kT$ is kinetic energy of the center-of-mass motion of the entire molecule, and the rest, $\tfrac{3}{2}(r - 1)kT$, is internal vibrational and rotational kinetic energy.
Chapter 29: Kinetic Theory of Gases: Equipartition of Energy and the Ideal Gas Law. 29.1 Introduction: Gas. A gas consists of a very large number of particles (typically 1024 or many orders of magnitude more) occupying a volume of space that is very large compared to the size (10−10 m ) of any typical atom or molecule.
Kinetic Theory. The kinetic theory of gases is the study of the microscopic behavior of molecules and the interactions which lead to macroscopic relationships like the ideal gas law.
Kinetic theory is the atomic description of gases as well as liquids and solids. It models the properties of matter in terms of continuous random motion of molecules. The temperature of gases is proportional to the average translational kinetic energy of molecules.
