During adiabatic expansion, the temperature of the system:
Correct answer: A. Decreases
- A. Decreases
- B. Increases
- C. Remains the same
- D. 0
Explanation
During adiabatic expansion, the system performs work on its surroundings without exchanging heat. This results in the internal energy of the system decreasing, leading to a decrease in temperature according to the ideal gas law.

About First Law of Thermodynamics
The first law relates heat supplied, work done and the change in internal energy through energy conservation. Problems use sign conventions and apply the law to isothermal, adiabatic, isobaric and isochoric processes. Internal energy is a state function, while heat and work depend on the path followed.
