Equation of State for Adiabatic Process on Ideal Gas

The equation of state for an adiabatic process performed on an ideal gas consisting of non-relativistic rigid triangular molecule in terms of pressure (P) and volume (V) is given by:

PV4/3 = constant

Explanation:

- The adiabatic process is a thermodynamic process in which there is no transfer of heat between the system and surroundings. Therefore, the internal energy of the gas remains constant.
- The ideal gas law is given by PV = nRT, where n is the number of moles of gas and R is the gas constant.
- For an adiabatic process, the ideal gas law can be modified to PVγ = constant, where γ is the ratio of specific heats for the gas.
- For a non-relativistic rigid triangular molecule, the degrees of freedom are f = 5, and the ratio of specific heats is γ = (f + 2)/f = 7/5.
- Substituting γ in the ideal gas law, we get PV7/5 = constant.
- However, we know that for an adiabatic process, the pressure and volume are related by PVγ = constant. Therefore, we can rewrite the equation as PV4/3 = constant, which is the correct equation of state for an adiabatic process performed on an ideal gas consisting of non-relativistic rigid triangular molecule.

Conclusion:

- The equation of state for an adiabatic process performed on an ideal gas consisting of non-relativistic rigid triangular molecule in terms of pressure (P) and volume (V) is given by PV4/3 = constant.
- This equation is derived from the ideal gas law and the relationship between pressure and volume for an adiabatic process.
