FALSIFICATIONS OF POISSON ADIABATE, HUGONIO ADIABATE, LAPLACE SOUND SPEEDS. MODERNIZATION OF FOUNDATIONS OF THERMODYNAMICS

Аннотация

The inequality of the universal gas constant of the difference in the heat capacity of a gas at constant
pressure with the heat capacity of a gas at a constant volume is proved. The falsifications of using the heat capacity
of a gas at constant pressure, false enthalpy, Poisson adiabat, Laplace sound speed, Hugoniot adiabat, based on the
use of the false equality of the universal gas constant difference in the heat capacity of a gas at constant pressure with
the heat capacity of a gas at a constant volume, have been established. The dependence of pressure on temperature in
an adiabatic gas with heat capacity at constant volume has been established. On the basis of the heat capacity of a gas
at a constant volume, new formulas are derived: the adiabats of an ideal gas, the speed of sound, and the adiabats on
a shock wave. The variability of pressure in the field of gravity is proved and it is indicated that the use of the
specific coefficient of ideal gas at constant pressure in gas-dynamic formulas is pointless. It is shown that the false
“basic formula of thermodynamics” implies the falseness of the equation with the specific heat capacity at constant
pressure. New formulas are given for the adiabat of an ideal gas, adiabat on a shock wave, and the speed of sound,
which, in principle, do not contain the coefficient of the specific heat capacity of a gas at constant pressure. It is
shown that the well-known equation of heat conductivity with the gas heat capacity coefficient at constant pressure
contradicts the basic energy balance equation with the gas heat capacity coefficient at constant volume.
