Answer:
In a reversible adiabatic expansion or compression, the temperature of an ideal gas does change. In a Joule-Thompson type of irreversible adiabatic expansion (e.g., in a closed container), the internal energy of the gas does not change. For an ideal gas, its internal energy depends only on its temperature.

It is a thermodynamic process, the Joule Thomson effect.
- When a fluid moves from high pressure to a low-pressure area, a phenomenon known as the "Joule Thomson Effect" occurs, which causes the fluid's temperature to alter.
- In addition to pressure, the expansion technique also affects how the temperature changes during the expansion process.
- The Joule-Thomson coefficient serves as a description of the Joule-Thomson effect.
- The Joule-Thomson effect's equation is JT = (T/P)H.
- In contrast to hydrogen or helium, a real gas has a cooling effect during the Joule Thomson expansion if the Joule Thomson coefficient is positive.
- At normal temperature, hydrogen has a negative Joule Thomson coefficient.
- Heat transfer is the basis for the Joule Thomson Effect.
- Adiabatic expansion is a reversible process in thermodynamics, and as a result, the Joule-Thomson effect is an irreversible process.
