In an adiabatic process, how does the temperature of a gas change as its volume decreases?
Correct answer: B. The temperature increases
- A. The temperature decreases
- B. The temperature increases
- C. The temperature remains constant
- D. Temperature increases first then decreases
Explanation
During an adiabatic process, when the volume of a gas decreases, its temperature increases due to the work done on the gas, which raises its internal energy.

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.
