My name is Alexander FufaeV and here I will explain the following topic:

## Formula

What do the formula symbols mean?

## Pressure before

Unit
Pressure of the ideal gas BEFORE the adiabatic process.

## Volume before

Unit
Volume of the ideal gas BEFORE the adiabatic process.

Unit
Adiabatic index is the quotient of heat capacities at constant pressure $$c_{\small{\Pi}}$$ and volume $$c_{\small{\text V}}$$.

For example, for monatomic gas: $$\gamma ~=~ \frac{5}{3}$$.

## Pressure after

Unit
Pressure of the ideal gas AFTER the adiabatic process.

## Volume after

Unit
Volume of the ideal gas AFTER the adiabatic process.
Explanation

## Video

The adiabatic equation describes the relationship between the pressure $$\mathit{\Pi}$$, volume $$V$$ and temperature $$T$$ of a gas during an adiabatic process. An adiabatic process is a thermodynamic process in which no heat is exchanged with the environment. This means that the change in the internal energy of the gas is exclusively due to the work performed on or by the gas.
