THEME: HEAT CAPACITY OF IDEAL GAS

PLAN:

• IDEAL GAS
• HEAT CAPACITY
• HEAT CAPACITY OF IDEAL GAS

An ideal gas is a gas whose molecules do not interact with each other at all; it does not take into account the specific volumes of the molecules that make up the gas. In cases where the density of any real gas is very small, it is by its nature I. g . approaches. At large values ​​of T-ra, i.e., when the average kinetic energy of molecules is much larger than the average potential energy created as a result of the interaction of molecules, real gases can be classified as I. g. can be considered as I. g. The internal energy of gas is equal to the sum of kinetic energies of chaotic (disordered) forward and rotational movement of all molecules that make up this gas, and kinetic and potential energies of chaotic vibrational motion of atoms in molecules. I. g with specific mass t. The equilibrium state of I. g, which represents the interrelationship of these parameters. The equation of state pV=~kT is usually called the Clapeyronmendeleev equation, where M is the molar mass of the gas. In solving many practical problems, real gases I. g. , which have a simple appearance, can be applied with great accuracy.

Under normal conditions, each molecule that makes up the gas has an average length of the free path of about 10-7 m and collides with other molecules several billion times in 1 second.
Migration events. If the density of molecules in the gas is different in different parts of the volume, or if the differences in the heat energy associated with the disordered movement of molecules have different values, then the transfer of mass, energy, momentum, etc. from one part of the gas out of equilibrium to the 2nd part occurs. Diffusion, thermal conductivity, internal friction, viscosity.
The internal energy of a given ideal gas is understood as the sum of the kinetic energies of the forward and rotational movement of all molecules that make up this gas and the kinetic and potential energies of the atoms in the molecules.
